Python-Semikolon: Warum Semikolon in Python erlaubt ist

Wenn Sie von C/C++, Java oder PHP kommen, sehen Sie viele Semikolons im Code. Die in diesen Anweisungen verwendeten Semikolons stellen einen Anweisungsabschluss dar. Der Hauptzweck von Semikolons (;)in verschiedenen Programmiersprachen besteht darin, die aktuelle Anweisung abzubrechen. 


Kann ich das Semikolon in Python verwenden? Ja, Sie können das Semikolon verwenden. Python schreibt nicht die Verwendung von Semikolons zum Trennen von Anweisungen vor. Semikolons können zum Trennen von Anweisungen verwendet werden, wenn Sie mehrere Anweisungen in derselben Zeile platzieren möchten. Semikolons werden nur in atypischen Situationen in Python verwendet.

Um Anweisungen in Python aufzuteilen, verwenden Sie die Semikolons.

Ein Semikolon in Python bezeichnet eine  Trennung  statt eine Beendigung. Siehe das folgende Beispiel.

print('Millie'); print('Bobby'); print('Brown')



Obwohl die Sprache ein Semikolon zum Trennen von Anweisungen unterstützt, verwenden die meisten Python-Programmierer es nie in ihrem Code. Der Grund ist einfach. Python soll eine saubere und lesbare Programmiersprache sein. Syntaktische Zeichen wie Semikolons sorgen für unnötige Unordnung.

Warum Semikolon in Python erlaubt ist

Warum sind Semikolons erlaubt? Nun, man kann sagen, dass es eine einfache Designentscheidung ist. Python ist ohne Semikolon gut, aber jemand dachte, es wäre schön, es der Sprache hinzuzufügen.

Wann sollte man ein Semikolon in Python verwenden?

Die wichtigste logische Frage ist, wann das Semikolon verwendet werden soll. Die Antwort ist, dass es bestimmte Situationen gibt, in denen Semikolons nützlich sind.

Wenn Sie in einem Interpreter REPL (Python Interactive Shell, IDLE oder ipython ) arbeiten, wird ein Wert des letzten Ausdrucks auf dem Bildschirm ausgegeben . Normalerweise ist dies das beabsichtigte Verhalten.

Ausführen eines Shell-Skripts.

Die häufigste Verwendung wäre, ein kurzes Skript aus der Shell mit python -c '<script>' auszuführen . In diesem Fall müssen wir viele Ausdrücke mit Semikolon getrennt eingeben, da wir hier keine Einrückung verwenden können.

python -c 'import math; t = math.pow(2, 3); print(int(t))’

Ein weiterer Anwendungsfall ist die Verwendung der exec()- Methode.

exec('for i in [11, 21, 46]: print(i);print(i*3)')

Das Semikolon ist zulässig. Aber das bedeutet nicht, dass Sie es verwenden sollten. Aber verwenden Sie es, wenn es notwendig ist.

Verwenden von Semikolons mit Schleifen in Python

Wenn Sie eine for-Schleife verwenden , kann ein Semikolon verwendet werden, wenn die gesamte Anweisung mit einer Schleife beginnt, und Sie verwenden ein Semikolon, um eine zusammenhängende Anweisung wie den Rumpf der Schleife zu bilden.

for i in range (3): print ('Homer') ; print('Simpson')

Das war es für dieses Tutorial.

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')

How to Remove all Duplicate Files on your Drive via Python

Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.


In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.

Heres a solution

Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.

But How do we do it?

If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?

The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.

There’s a variety of hashing algorithms out there such as

  • md5
  • sha1
  • sha224, sha256, sha384 and sha512

How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

1. init

class AnyClass:
    def __init__():
        print("Init called on its own")
obj = AnyClass()

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

Init called on its own

2. add

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

class AnyClass:
    def __init__(self, var):
        self.some_var = var
    def __add__(self, other_obj):
        print("Calling the add method")
        return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
