Precedence And Associativity — Part 1 MCQs with Explanations

Multiplication and division have the same precedence and are evaluated left to right.

Exponentiation is right-associative, so the expression is evaluated as 2 ** (3 ** 2).

In Python, operators have specific precedence levels that determine the order in which operations are performed. Subtraction (-) and addition (+) operators have the same precedence level and are evaluated from left to right (left associativity). In the expression 5 - 2 + 1: First, 5 - 2 is evaluated, resulting in 3. Then, 3 + 1 is evaluated, resulting in 4. Thus, the result of the expression 5 - 2 + 1 is 4.

Multiplication and modulo have the same precedence and are evaluated left to right.

The // and / operators have the same precedence and are evaluated left to right.

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

Division has left-to-right associativity, so the result is 0.5.

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.

Multiplication and division have the same precedence and are evaluated left to right.

Multiplication and modulo have the same precedence and are evaluated left to right.

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.

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 has higher precedence, so 4 ** 2 is evaluated first, then multiplication and addition follow.

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

Addition and subtraction have the same precedence and are evaluated left to right.

Division has higher precedence, so 6 / 2 is evaluated first, then subtracted from 8.

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

The exponentiation (**) operator has the highest precedence.

Exponentiation has higher precedence, so 3 ** 2 is evaluated first, then floor division.

Exponentiation has higher precedence, so 2 ** 2 is evaluated first, then multiplication and division follow.
