Vriable and Data Types In Python

In Python, variables are used to store data values. A variable is created the moment you assign a value to it. Python is a dynamically typed language, so you don't need to declare the type of variable explicitly. The type is inferred at runtime based on the value assigned.

Example:

python

Copy

Edit

name = "Mahesh"      # str

age = 25             # int

price = 99.99        # float

is_active = True     # bool

Common Data Types in Python:

int – Used to represent whole numbers. Example: 10, -5

float – Used for decimal or floating-point numbers. Example: 3.14, -0.75

str – String type to store text. Example: "Hello", 'Python'

bool – Boolean type, representing True or False

list – Ordered, changeable collection. Example: [1, 2, 3, "apple"]

tuple – Ordered, unchangeable collection. Example: (10, 20, 30)

 in 

dict – Dictionary to store key-value pairs. Example: {"name": "Mahesh", "age": 25}

set – Unordered collection of unique items. Example: {1, 2, 3}

Python also supports advanced data types like complex numbers, bytes, and custom classes. Understanding variables and data types is the first step in mastering Python programming. It helps in storing, accessing, and manipulating data effectively in your programs.
