Line 1

x = 42 creates an integer object and binds name 'x' to it.

Yeh approach kyun?

Python stores every value as an object on the heap. The variable x is just a label pointing to the object 42. This makes reassignment cheap — you just point the label elsewhere.

Structured Explanation

Overview

Variables data store karne ke containers hain bhai. Python mein int, float, str, bool — ye sab types hain.

Analogy

Variable ek labelled dabba hai — label naam hai, andar ka saman value hai.

Step-by-step

Meaningful naam choose karo
= se value assign karo
Python automatically type detect kar leta hai
Different type se reassign bhi kar sakte ho

Visual

age = 25 # int height = 1.75 # float name = "Alice" # str active = True # bool

Common mistakes

Variable name mein space daal dena
= (assign) aur == (compare) ka confusion
Text ke liye quotes bhool jaana

Practice questions

Naam, umar, height ke variables banao
type() se type check karo

Complexity	Operations
O(1)	1
O(log n)	3
O(n)	8
O(n log n)	24
O(n²)	64

Challenge

Apni age (int), height (float), aur naam (str) ke liye variables banao.

Hint

type() se variable ka type check karo. f-strings se printing easy hoti hai.
