Assignment Operators

Assignment operators are used to store values in variables or update them.

---

1. Store Value (=)

The single equals sign (=) is the most basic assignment operator. It stores the value on the right inside the variable on the left.

score = 100
name = "Rahul"

2. Shortcut Operators (Compound Assignment)

Sometimes you want to update the value of an existing variable. For example, if you are building a game and the player scores, you want to add 5 to their current score:

score = 100
# The long way:
score = score + 5

Python gives you shortcut operators to update a variable in place:

Add and Assign (+=)

Adds a number to a variable and updates it.

score = 100
score += 5  # Same as: score = score + 5 (score is now 105)

Subtract and Assign (-=)

Subtracts a number from a variable and updates it.

score = 100
score -= 10  # Same as: score = score - 10 (score is now 90)

Multiply and Assign (*=)

Multiplies the variable and updates it.

score = 10
score *= 3  # Same as: score = score * 3 (score is now 30)

Divide and Assign (/=)

Divides the variable and updates it.

score = 10
score /= 2  # Same as: score = score / 2 (score is now 5.0)

Floor Divide and Assign (//=)

Floor divides the variable and updates it.

score = 10
score //= 3  # Same as: score = score // 3 (score is now 3)

Modulus and Assign (%=)

Updates the variable with the leftover remainder.

score = 10
score %= 3  # Same as: score = score % 3 (score is now 1)
