Guest Post: Calling The Docker CLI From Python with Python-on-whales
At Docker, we are incredibly proud of our vibrant, diverse and creative community. From time to time, we feature cool contributions from the community on our blog to highlight some of the great work our community does. The following is a guest post by Docker community member Gabriel de Marmiesse. Are you working on something awesome with Docker? Send your contributions to William Quiviger (@william) on the Docker Community Slack and we might feature your work!
The most common way to call and control Docker is by using the command line.
With the increased usage of Docker, users want to call Docker from programming languages other than shell. One popular way to use Docker from Python has been to use docker-py. This library has had so much success that even docker-compose is written in Python, and leverages docker-py.
The goal of docker-py though is not to replicate the Docker client (written in Golang), but to talk to the Docker Engine HTTP API. The Docker client is extremely complex and is hard to duplicate in another language. Because of this, a lot of features that were in the Docker client could not be available in docker-py. Sometimes users would sometimes get frustrated because docker-py did not behave exactly like the CLI.
Today, we’re presenting a new project built by Gabriel de Marmiesse from the Docker community: Python-on-whales. The goal of this project is to have a 1-to-1 mapping between the Docker CLI and the Python library. We do this by communicating with the Docker CLI instead of calling directly the Docker Engine HTTP API.

Python Global Variables – How to Define a Global Variable Example
In this article, you will learn the basics of global variables.
To begin with, you will learn how to declare variables in Python and what the term 'variable scope' actually means.
Then, you will learn the differences between local and global variables and understand how to define global variables and how to use the global keyword.
What Are Variables in Python and How Do You Create Them? An Introduction for Beginners
You can think of variables as storage containers.
They are storage containers for holding data, information, and values that you would like to save in the computer's memory. You can then reference or even manipulate them at some point throughout the life of the program.
A variable has a symbolic name, and you can think of that name as the label on the storage container that acts as its identifier.
The variable name will be a reference and pointer to the data stored inside it. So, there is no need to remember the details of your data and information – you only need to reference the variable name that holds that data and information.
When giving a variable a name, make sure that it is descriptive of the data it holds. Variable names need to be clear and easily understandable both for your future self and the other developers you may be working with.
Now, let's see how to actually create a variable in Python.
When declaring variables in Python, you don't need to specify their data type.
For example, in the C programming language, you have to mention explicitly the type of data the variable will hold.
So, if you wanted to store your age which is an integer, or int type, this is what you would have to do in C:
#include <stdio.h>
int main(void)
{
int age = 28;
// 'int' is the data type
// 'age' is the name
// 'age' is capable of holding integer values
// positive/negative whole numbers or 0
// '=' is the assignment operator
// '28' is the value
}
However, this is how you would write the above in Python:
age = 28
#'age' is the variable name, or identifier
# '=' is the assignment operator
#'28' is the value assigned to the variable, so '28' is the value of 'age'
The variable name is always on the left-hand side, and the value you want to assign goes on the right-hand side after the assignment operator.
Keep in mind that you can change the values of variables throughout the life of a program:
my_age = 28
print(f"My age in 2022 is {my_age}.")
my_age = 29
print(f"My age in 2023 will be {my_age}.")
#output
#My age in 2022 is 28.
#My age in 2023 will be 29.
You keep the same variable name, my_age, but only change the value from 28 to 29.
What Does Variable Scope in Python Mean?
Variable scope refers to the parts and boundaries of a Python program where a variable is available, accessible, and visible.
There are four types of scope for Python variables, which are also known as the LEGB rule:
- Local,
- Enclosing,
- Global,
- Built-in.
For the rest of this article, you will focus on learning about creating variables with global scope, and you will understand the difference between the local and global variable scopes.
How to Create Variables With Local Scope in Python
Variables defined inside a function's body have local scope, which means they are accessible only within that particular function. In other words, they are 'local' to that function.
You can only access a local variable by calling the function.
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#output
#The best place to learn to code is with freeCodeCamp!
Look at what happens when I try to access that variable with a local scope from outside the function's body:
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#try to print local variable 'coding_website' from outside the function
print(coding_website)
#output
#NameError: name 'coding_website' is not defined
It raises a NameError because it is not 'visible' in the rest of the program. It is only 'visible' within the function where it was defined.
How to Create Variables With Global Scope in Python
When you define a variable outside a function, like at the top of the file, it has a global scope and it is known as a global variable.
A global variable is accessed from anywhere in the program.
You can use it inside a function's body, as well as access it from outside a function:
#create a global variable
coding_website = "freeCodeCamp"
def learn_to_code():
#access the variable 'coding_website' inside the function
print(f"The best place to learn to code is with {coding_website}!")
#call the function
learn_to_code()
#access the variable 'coding_website' from outside the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
What happens when there is a global and local variable, and they both have the same name?
#global variable
city = "Athens"
def travel_plans():
#local variable with the same name as the global variable
city = "London"
print(f"I want to visit {city} next year!")
#call function - this will output the value of local variable
travel_plans()
#reference global variable - this will output the value of global variable
print(f"I want to visit {city} next year!")
#output
#I want to visit London next year!
#I want to visit Athens next year!
In the example above, maybe you were not expecting that specific output.
Maybe you thought that the value of city would change when I assigned it a different value inside the function.
Maybe you expected that when I referenced the global variable with the line print(f" I want to visit {city} next year!"), the output would be #I want to visit London next year! instead of #I want to visit Athens next year!.
However, when the function was called, it printed the value of the local variable.
Then, when I referenced the global variable outside the function, the value assigned to the global variable was printed.
They didn't interfere with one another.
That said, using the same variable name for global and local variables is not considered a best practice. Make sure that your variables don't have the same name, as you may get some confusing results when you run your program.
How to Use the global Keyword in Python
What if you have a global variable but want to change its value inside a function?
Look at what happens when I try to do that:
#global variable
city = "Athens"
def travel_plans():
#First, this is like when I tried to access the global variable defined outside the function.
# This works fine on its own, as you saw earlier on.
print(f"I want to visit {city} next year!")
#However, when I then try to re-assign a different value to the global variable 'city' from inside the function,
#after trying to print it,
#it will throw an error
city = "London"
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#output
#UnboundLocalError: local variable 'city' referenced before assignment
By default Python thinks you want to use a local variable inside a function.
So, when I first try to print the value of the variable and then re-assign a value to the variable I am trying to access, Python gets confused.
The way to change the value of a global variable inside a function is by using the global keyword:
#global variable
city = "Athens"
#print value of global variable
print(f"I want to visit {city} next year!")
def travel_plans():
global city
#print initial value of global variable
print(f"I want to visit {city} next year!")
#assign a different value to global variable from within function
city = "London"
#print new value
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#print value of global variable
print(f"I want to visit {city} next year!")
Use the global keyword before referencing it in the function, as you will get the following error: SyntaxError: name 'city' is used prior to global declaration.
Earlier, you saw that you couldn't access variables created inside functions since they have local scope.
The global keyword changes the visibility of variables declared inside functions.
def learn_to_code():
global coding_website
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#access variable from within the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
Conclusion
And there you have it! You now know the basics of global variables in Python and can tell the differences between local and global variables.
I hope you found this article useful.
You'll start from the basics and learn in an interactive and beginner-friendly way. You'll also build five projects at the end to put into practice and help reinforce what you've learned.
Thanks for reading and happy coding!

Variables Globales De Python: Cómo Definir Un Ejemplo De Variable Glob
En este artículo, aprenderá los conceptos básicos de las variables globales.
Para empezar, aprenderá cómo declarar variables en Python y qué significa realmente el término 'ámbito de variable'.
Luego, aprenderá las diferencias entre variables locales y globales y comprenderá cómo definir variables globales y cómo usar la globalpalabra clave.
¿Qué son las variables en Python y cómo se crean? Una introducción para principiantes
Puede pensar en las variables como contenedores de almacenamiento .
Son contenedores de almacenamiento para almacenar datos, información y valores que le gustaría guardar en la memoria de la computadora. Luego puede hacer referencia a ellos o incluso manipularlos en algún momento a lo largo de la vida del programa.
Una variable tiene un nombre simbólico y puede pensar en ese nombre como la etiqueta en el contenedor de almacenamiento que actúa como su identificador.
El nombre de la variable será una referencia y un puntero a los datos almacenados en su interior. Por lo tanto, no es necesario recordar los detalles de sus datos e información; solo necesita hacer referencia al nombre de la variable que contiene esos datos e información.
Al dar un nombre a una variable, asegúrese de que sea descriptivo de los datos que contiene. Los nombres de las variables deben ser claros y fácilmente comprensibles tanto para usted en el futuro como para los otros desarrolladores con los que puede estar trabajando.
Ahora, veamos cómo crear una variable en Python.
Al declarar variables en Python, no necesita especificar su tipo de datos.
Por ejemplo, en el lenguaje de programación C, debe mencionar explícitamente el tipo de datos que contendrá la variable.
Entonces, si quisiera almacenar su edad, que es un número entero, o inttipo, esto es lo que tendría que hacer en C:
#include <stdio.h>
int main(void)
{
int age = 28;
// 'int' is the data type
// 'age' is the name
// 'age' is capable of holding integer values
// positive/negative whole numbers or 0
// '=' is the assignment operator
// '28' is the value
}
Sin embargo, así es como escribirías lo anterior en Python:
age = 28
#'age' is the variable name, or identifier
# '=' is the assignment operator
#'28' is the value assigned to the variable, so '28' is the value of 'age'
El nombre de la variable siempre está en el lado izquierdo y el valor que desea asignar va en el lado derecho después del operador de asignación.
Tenga en cuenta que puede cambiar los valores de las variables a lo largo de la vida de un programa:
my_age = 28
print(f"My age in 2022 is {my_age}.")
my_age = 29
print(f"My age in 2023 will be {my_age}.")
#output
#My age in 2022 is 28.
#My age in 2023 will be 29.
Mantienes el mismo nombre de variable my_age, pero solo cambias el valor de 28a 29.
¿Qué significa el alcance variable en Python?
El alcance de la variable se refiere a las partes y los límites de un programa de Python donde una variable está disponible, accesible y visible.
Hay cuatro tipos de alcance para las variables de Python, que también se conocen como la regla LEGB :
- local ,
- Encerrando ,
- globales ,
- Incorporado .
En el resto de este artículo, se centrará en aprender a crear variables con alcance global y comprenderá la diferencia entre los alcances de variables locales y globales.
Cómo crear variables con alcance local en Python
Las variables definidas dentro del cuerpo de una función tienen alcance local , lo que significa que solo se puede acceder a ellas dentro de esa función en particular. En otras palabras, son 'locales' para esa función.
Solo puede acceder a una variable local llamando a la función.
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#output
#The best place to learn to code is with freeCodeCamp!
Mire lo que sucede cuando trato de acceder a esa variable con un alcance local desde fuera del cuerpo de la función:
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#try to print local variable 'coding_website' from outside the function
print(coding_website)
#output
#NameError: name 'coding_website' is not defined
Plantea un NameErrorporque no es 'visible' en el resto del programa. Solo es 'visible' dentro de la función donde se definió.
Cómo crear variables con alcance global en Python
Cuando define una variable fuera de una función, como en la parte superior del archivo, tiene un alcance global y se conoce como variable global.
Se accede a una variable global desde cualquier parte del programa.
Puede usarlo dentro del cuerpo de una función, así como acceder desde fuera de una función:
#create a global variable
coding_website = "freeCodeCamp"
def learn_to_code():
#access the variable 'coding_website' inside the function
print(f"The best place to learn to code is with {coding_website}!")
#call the function
learn_to_code()
#access the variable 'coding_website' from outside the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
¿Qué sucede cuando hay una variable global y local, y ambas tienen el mismo nombre?
#global variable
city = "Athens"
def travel_plans():
#local variable with the same name as the global variable
city = "London"
print(f"I want to visit {city} next year!")
#call function - this will output the value of local variable
travel_plans()
#reference global variable - this will output the value of global variable
print(f"I want to visit {city} next year!")
#output
#I want to visit London next year!
#I want to visit Athens next year!
En el ejemplo anterior, tal vez no esperaba ese resultado específico.
Tal vez pensaste que el valor de citycambiaría cuando le asignara un valor diferente dentro de la función.
Tal vez esperabas que cuando hice referencia a la variable global con la línea print(f" I want to visit {city} next year!"), la salida sería en #I want to visit London next year!lugar de #I want to visit Athens next year!.
Sin embargo, cuando se llamó a la función, imprimió el valor de la variable local.
Luego, cuando hice referencia a la variable global fuera de la función, se imprimió el valor asignado a la variable global.
No interfirieron entre sí.
Dicho esto, usar el mismo nombre de variable para variables globales y locales no se considera una buena práctica. Asegúrese de que sus variables no tengan el mismo nombre, ya que puede obtener algunos resultados confusos cuando ejecute su programa.
Cómo usar la globalpalabra clave en Python
¿Qué sucede si tiene una variable global pero desea cambiar su valor dentro de una función?
Mira lo que sucede cuando trato de hacer eso:
#global variable
city = "Athens"
def travel_plans():
#First, this is like when I tried to access the global variable defined outside the function.
# This works fine on its own, as you saw earlier on.
print(f"I want to visit {city} next year!")
#However, when I then try to re-assign a different value to the global variable 'city' from inside the function,
#after trying to print it,
#it will throw an error
city = "London"
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#output
#UnboundLocalError: local variable 'city' referenced before assignment
Por defecto, Python piensa que quieres usar una variable local dentro de una función.
Entonces, cuando intento imprimir el valor de la variable por primera vez y luego reasignar un valor a la variable a la que intento acceder, Python se confunde.
La forma de cambiar el valor de una variable global dentro de una función es usando la globalpalabra clave:
#global variable
city = "Athens"
#print value of global variable
print(f"I want to visit {city} next year!")
def travel_plans():
global city
#print initial value of global variable
print(f"I want to visit {city} next year!")
#assign a different value to global variable from within function
city = "London"
#print new value
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#print value of global variable
print(f"I want to visit {city} next year!")
Utilice la globalpalabra clave antes de hacer referencia a ella en la función, ya que obtendrá el siguiente error: SyntaxError: name 'city' is used prior to global declaration.
Anteriormente, vio que no podía acceder a las variables creadas dentro de las funciones ya que tienen un alcance local.
La globalpalabra clave cambia la visibilidad de las variables declaradas dentro de las funciones.
def learn_to_code():
global coding_website
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#access variable from within the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
Conclusión
¡Y ahí lo tienes! Ahora conoce los conceptos básicos de las variables globales en Python y puede distinguir las diferencias entre las variables locales y globales.
Espero que hayas encontrado útil este artículo.
Comenzará desde lo básico y aprenderá de una manera interactiva y amigable para principiantes. También construirá cinco proyectos al final para poner en práctica y ayudar a reforzar lo que ha aprendido.

Pythonグローバル変数–グローバル変数の例を定義する方法
この記事では、グローバル変数の基本を学びます。
まず、Pythonで変数を宣言する方法と、「変数スコープ」という用語が実際に何を意味するかを学習します。
次に、ローカル変数とグローバル変数の違いを学び、グローバル変数の定義方法とglobalキーワードの使用方法を理解します。
Pythonの変数とは何ですか？どのように作成しますか？初心者のための紹介
変数はストレージコンテナと考えることができます。
これらは、コンピュータのメモリに保存したいデータ、情報、および値を保持するためのストレージコンテナです。その後、プログラムの存続期間中のある時点でそれらを参照したり、操作したりすることもできます。
変数にはシンボリック名があり、その名前は、その識別子として機能するストレージコンテナのラベルと考えることができます。
変数名は、その中に格納されているデータへの参照とポインターになります。したがって、データと情報の詳細を覚えておく必要はありません。そのデータと情報を保持する変数名を参照するだけで済みます。
変数に名前を付けるときは、変数が保持するデータを説明していることを確認してください。変数名は、将来の自分自身と一緒に作業する可能性のある他の開発者の両方にとって、明確で簡単に理解できる必要があります。
それでは、Pythonで実際に変数を作成する方法を見てみましょう。
Pythonで変数を宣言するときは、データ型を指定する必要はありません。
たとえば、Cプログラミング言語では、変数が保持するデータの型を明示的に指定する必要があります。
したがって、整数またはint型である年齢を格納したい場合、これはCで行う必要があることです。
#include <stdio.h>
int main(void)
{
int age = 28;
// 'int' is the data type
// 'age' is the name
// 'age' is capable of holding integer values
// positive/negative whole numbers or 0
// '=' is the assignment operator
// '28' is the value
}
ただし、これはPythonで上記を記述する方法です。
age = 28
#'age' is the variable name, or identifier
# '=' is the assignment operator
#'28' is the value assigned to the variable, so '28' is the value of 'age'
変数名は常に左側にあり、代入する値は代入演算子の後に右側に配置されます。
プログラムの存続期間中、変数の値を変更できることに注意してください。
my_age = 28
print(f"My age in 2022 is {my_age}.")
my_age = 29
print(f"My age in 2023 will be {my_age}.")
#output
#My age in 2022 is 28.
#My age in 2023 will be 29.
同じ変数名を保持しますが、値をからにmy_age変更するだけです。2829
Pythonの可変スコープとはどういう意味ですか？
変数スコープとは、変数が利用可能で、アクセス可能で、表示可能なPythonプログラムの部分と境界を指します。
Python変数のスコープには4つのタイプがあり、 LEGBルールとも呼ばれます。
- 局所、
- 囲み、
- グローバル、
- ビルトイン。
この記事の残りの部分では、グローバルスコープを使用した変数の作成について学習することに焦点を当て、ローカル変数スコープとグローバル変数スコープの違いを理解します。
Pythonでローカルスコープを使用して変数を作成する方法
関数の本体内で定義された変数にはローカルスコープがあります。つまり、その特定の関数内でのみアクセスできます。言い換えれば、それらはその関数に対して「ローカル」です。
ローカル変数にアクセスするには、関数を呼び出す必要があります。
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#output
#The best place to learn to code is with freeCodeCamp!
関数の本体の外部からローカルスコープを使用してその変数にアクセスしようとするとどうなるかを見てください。
def learn_to_code():
#create local variable
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#try to print local variable 'coding_website' from outside the function
print(coding_website)
#output
#NameError: name 'coding_website' is not defined
NameErrorプログラムの残りの部分では「表示」されないため、aが発生します。定義された関数内でのみ「表示」されます。
Pythonでグローバルスコープを使用して変数を作成する方法
ファイルの先頭など、関数の外部で変数を定義すると、その変数はグローバルスコープを持ち、グローバル変数と呼ばれます。
グローバル変数は、プログラムのどこからでもアクセスできます。
関数の本体内で使用することも、関数の外部からアクセスすることもできます。
#create a global variable
coding_website = "freeCodeCamp"
def learn_to_code():
#access the variable 'coding_website' inside the function
print(f"The best place to learn to code is with {coding_website}!")
#call the function
learn_to_code()
#access the variable 'coding_website' from outside the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
グローバル変数とローカル変数があり、両方が同じ名前の場合はどうなりますか？
#global variable
city = "Athens"
def travel_plans():
#local variable with the same name as the global variable
city = "London"
print(f"I want to visit {city} next year!")
#call function - this will output the value of local variable
travel_plans()
#reference global variable - this will output the value of global variable
print(f"I want to visit {city} next year!")
#output
#I want to visit London next year!
#I want to visit Athens next year!
上記の例では、その特定の出力を期待していなかった可能性があります。
city関数内で別の値を割り当てたときに、の値が変わると思ったかもしれません。
たぶん、私が行でグローバル変数を参照したときprint(f" I want to visit {city} next year!")、出力は#I want to visit London next year!の代わりになると予想しました#I want to visit Athens next year!。
ただし、関数が呼び出されると、ローカル変数の値が出力されます。
次に、関数の外部でグローバル変数を参照すると、グローバル変数に割り当てられた値が出力されました。
彼らはお互いに干渉しませんでした。
ただし、グローバル変数とローカル変数に同じ変数名を使用することは、ベストプラクティスとは見なされません。プログラムを実行すると混乱する結果が生じる可能性があるため、変数の名前が同じでないことを確認してください。
Pythonでキーワードを使用する方法global
グローバル変数があり、関数内でその値を変更したい場合はどうなりますか？
私がそれをしようとすると何が起こるか見てください：
#global variable
city = "Athens"
def travel_plans():
#First, this is like when I tried to access the global variable defined outside the function.
# This works fine on its own, as you saw earlier on.
print(f"I want to visit {city} next year!")
#However, when I then try to re-assign a different value to the global variable 'city' from inside the function,
#after trying to print it,
#it will throw an error
city = "London"
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#output
#UnboundLocalError: local variable 'city' referenced before assignment
デフォルトでは、Pythonは関数内でローカル変数を使用したいと考えています。
そのため、最初に変数の値を出力してから、アクセスしようとしている変数に値を再割り当てしようとすると、Pythonが混乱します。
関数内のグローバル変数の値を変更する方法は、次のglobalキーワードを使用することです。
#global variable
city = "Athens"
#print value of global variable
print(f"I want to visit {city} next year!")
def travel_plans():
global city
#print initial value of global variable
print(f"I want to visit {city} next year!")
#assign a different value to global variable from within function
city = "London"
#print new value
print(f"I want to visit {city} next year!")
#call function
travel_plans()
#print value of global variable
print(f"I want to visit {city} next year!")
global次のエラーが発生するため、関数でキーワードを参照する前にキーワードを使用してくださいSyntaxError: name 'city' is used prior to global declaration。
以前、関数内で作成された変数はローカルスコープを持っているため、それらにアクセスできないことを確認しました。
globalキーワードは、関数内で宣言された変数の可視性を変更します。
def learn_to_code():
global coding_website
coding_website = "freeCodeCamp"
print(f"The best place to learn to code is with {coding_website}!")
#call function
learn_to_code()
#access variable from within the function
print(coding_website)
#output
#The best place to learn to code is with freeCodeCamp!
#freeCodeCamp
