📝 Assignment & Compound Operators

Last Updated: 15th August 2025

📌 What is Assignment (=)?

  • The assignment operator = stores a value into a variable.
  • It simply places the value on the right into the variable on the left.

Hinglish Tip 🗣: = ka matlab hai “variable ko value dedo” — jaise x = 10 matlab x ke andar 10 daal do.

Example:

x = 10      # x now holds 10
y = 3.5     # y now holds 3.5

📌 Compound Operator

  • Compound assignment operators combine an operation and assignment in one step.
  • Instead of writing x = x + 5, you can write x += 5.
  • They work for arithmetic and bitwise operations (use bitwise versions with integers).

Hinglish Tip 🗣: x += 5 ek chhota shortcut hai x = x + 5 ka.

OperatorMeaningEquivalent Long Form
=Assignx = 10
+=Add and assignx += 5 → x = x + 5
-=Subtract and assignx -= 3 → x = x - 3
*=Multiply and assignx *= 2 → x = x * 2
/=Divide and assign (float result) x /= 4 → x = x / 4
//=Floor divide and assignx //= 2 → x = x // 2
%=Modulus and assignx %= 3 → x = x % 3
**=Power and assignx **= 2 → x = x ** 2
&=Bitwise AND and assignx &= 3 → x = x & 3
|=Bitwise OR and assignx |= 2 → x = x | 2
^=Bitwise XOR and assignx ^= 4 → x = x ^ 4
<<=Left shift and assignx <<= 1 → x = x << 1
>>=Right shift and assignx >>= 2 → x = x >> 2

Example:

x = 10
x += 5
print(x)    # Output: 15

y = 12
y -= 2      # y becomes 10

a = 4
a *= 3      # a becomes 12

b = 20
b /= 4      # b becomes 5.0   (note: division gives float)

💡 Don’t worry! For Bitwise Operator ,We will cover in upcoming section.

💡 Quick Practice

  • num = 100 → reduce by 25 using a compound operator (one line).
  • x = 4 → multiply by 3 using *= and print.
  • val = 50 → divide by 5 using /= and show the type of result.
  • m = -9 → do m //= 4 and m %= 4 then print results.
