Python Operators

Operators do work on values. Arithmetic: + - * / // % **. / is true division (7/2 is 3.5). // is floor division (7//2 is 3). ** is power. % is remainder — even/odd uses n % 2 == 0.

Compare with == != > < >= <=. Result is True or False. Logical: and, or, not. Membership: "A" in "Asha". Identity: is compares the same object, == compares value. Freshers write if n = 2 (assign) instead of == (compare).

Board — print(7 / 2, 7 // 2) → 3.5 3. Say that out loud. Then "sha" in "Asha" → True.

Python Operators — output — 3.333…, 3, 1, True. 10//3 is 3. "a" is inside "Asha".

Exam tip

Explain // vs / and in with one tiny example.

Example

# Operators
a, b = 10, 3
print(a / b)
print(a // b)
print(a % b)
print("a" in "Asha")

Python Operators — output: 3.333…, 3, 1, True. 10//3 is 3. "a" is inside "Asha".

Short notes

DefOperators act on values.
Rule// floor, / true division.
Trap= inside if instead of ==.
Rememberin / is.
