Python Operator Precedence: MCQs for Exam Prep

In Python, expressions are evaluated according to operator precedence, which determines the order in which operations are performed.

The multiplication operator (*) has higher precedence than the addition operator (+).

Therefore, in the expression 3 + 4 * 5, the multiplication is performed first.

First step: 4 * 5 = 20

Second step: 3 + 20 = 23

Thus, the final result of the expression is 23.

Hence, the correct answer is Option B: 23.

Parentheses have the highest precedence, so the expression inside them is evaluated first.

Parentheses have the highest precedence, so the expression inside them is evaluated first.

Exponentiation has higher precedence than division, so 2 ** 2 is evaluated first.

Exponentiation has higher precedence, so 3 ** 2 is evaluated first, then modulo, and finally addition.

Exponentiation and multiplication have the same precedence and are evaluated left to right.
