Variables are fundamental in programming. In Python, you can assign values to variables using the = operator. Here's how it works:

Basic Syntax

variable_name = value
  • Example: 
    x = 10
name = "Python"
is_active = True

Data Types

Python automatically infers the data type based on the value:

  • Integer: age = 25
  • String: message = "Hello, world!"
  • Boolean: flag = False

Variable Rules

  • Naming: Use letters, underscores (_), or numbers (but not starting with a number).
    ✅ valid_var
    ❌ 1invalid_var
  • Scope: Variables defined inside a function are local to that function.

Practice

Try modifying these variables in your code:

count = 5
count += 1  # Now count is 6
