Basic Variable Types in Python

This written lesson is part of Banana Chip Tech’s Python Crash Course. For video lectures, programming homework assignments, and other content please visit our website.

Variables are ways that we can store information for use later on in a program. For this reason, they are incredibly helpful when programming. The way that I like to think about variables are like jars where we can stuff information in and then take information out later. A good real world example of what a variable does can be found in food containers. The food container itself would be the variable and the food that it holds would be the data that a variable would hold. For instance, we can store some peanut butter in our peanut butter jar. We can then take our peanut butter out of the jar and use it when we want to make our peanut butter and jelly sandwich. Similarly, we can have a pizza box which is holding our pizza. Later on when we are hungry, we can take out a piece of pizza and eat it. Both the peanut butter jar and pizza box act as storage containers, but _what _they store is different. All python variables store information, but the type of information that they store differs.

While python doesn’t force you to document what specific type of variable you’re going to be using, knowing the type of variable used can be critical for the success of your program. I like to classify python variables into two distinct types: basic variable types and data structure variable types. In this tutorial, we talk about the different basic variable types.

Basic variable types contain only a single piece of information. These basic variable types are like our peanut butter jar that only stores peanut butter. We can’t store cheese or bread in our peanut butter jar; we can only store peanut butter!

The first basic variable type that we will discuss is the integer (int). Ints are whole numbers that don’t have a decimal. They can be positive or negative as long as they don’t have a decimal. The following code provides a demonstration of creating an int. Notice that the equal sign is used to assign the value 3 to the variable named myint. For simplicity sake, I recommend using only letters and underscores in your variable names. Avoid using any keywords (ie: for, in, while, if, etc) in your variable names. Following these recommendations will help you avoid any invalid variable names!

Basic Data Types in Python | Python Web Development For Beginners

At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

Table of Contents  hide

I Mutable objects

II Immutable objects

III Built-in data types in Python

Mutable objects

The Size and declared value and its sequence of the object can able to be modified called mutable objects.

Mutable Data Types are list, dict, set, byte array

Immutable objects

The Size and declared value and its sequence of the object can able to be modified.

Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.

id() and type() is used to know the Identity and data type of the object

a**=25+**85j

type**(a)**

output**:<class’complex’>**

b**={1:10,2:“Pinky”****}**

id**(b)**

output**:**238989244168

Built-in data types in Python

a**=str(“Hello python world”)****#str**

b**=int(18)****#int**

c**=float(20482.5)****#float**

d**=complex(5+85j)****#complex**

e**=list((“python”,“fast”,“growing”,“in”,2018))****#list**

f**=tuple((“python”,“easy”,“learning”))****#tuple**

g**=range(10)****#range**

h**=dict(name=“Vidu”,age=36)****#dict**

i**=set((“python”,“fast”,“growing”,“in”,2018))****#set**

j**=frozenset((“python”,“fast”,“growing”,“in”,2018))****#frozenset**

k**=bool(18)****#bool**

l**=bytes(8)****#bytes**

m**=bytearray(8)****#bytearray**

n**=memoryview(bytes(18))****#memoryview**

Numbers (int,Float,Complex)

Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.

#signed interger

age**=**18

print**(age)**

Output**:**18

Python supports 3 types of numeric data.

int (signed integers like 20, 2, 225, etc.)

float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)

complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)

A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).

String

The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.

# String Handling

‘Hello Python’

#single (') Quoted String

“Hello Python”

# Double (") Quoted String

“”“Hello Python”“”

‘’‘Hello Python’‘’

# triple (‘’') (“”") Quoted String

In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.

The operator “+” is used to concatenate strings and “*” is used to repeat the string.

“Hello”+“python”

output**:****‘Hello python’**

"python "*****2

'Output : Python python ’

I. About Python 🐍

Created by Dutch programmer Guido van Rossum at Centrum Wiskunde & Informatica, Python made its debut in 1991. Over thirty years it has gained popularity earned a reputation of being the “Swiss army knife of programming languages.” Here are a few reasons why:

In emerging fields like data science, artificial intelligence, and machine learning, a robust community, plenty of packages, paradigm flexibility, and syntactical simplicity, allow beginners and professionals to focus on insights and innovation.
