Which expression evaluates first in: x = 3 + 2 * 4?

• 3 + 2

• 2 * 4

• x = 3

• x =

Answer explanation

In the expression x = 3 + 2 * 4, multiplication has higher precedence than addition. Therefore, 2 * 4 is evaluated first, resulting in 8, before adding 3.

How is the expression evaluated: not True and False?

• None

• False

• True

• Error

Answer explanation

The expression 'not True' evaluates to 'False'. Then, 'False and False' results in 'False'. Therefore, the final evaluation of 'not True and False' is 'False'.

Which is the result of 3 ** 2 % 5?

• 4

• 1

• 9

• 0

Answer explanation

To solve 3 ** 2 % 5, first calculate 3 ** 2, which is 9. Then, find 9 % 5, which gives a remainder of 4. Therefore, the correct answer is 4.

Which operator is evaluated first: *, +, or -?

• +

• -

• *

• =

Answer explanation

In arithmetic operations, the multiplication operator (*) has the highest precedence, meaning it is evaluated first. Therefore, among *, +, and -, the correct answer is *.

Which does 7 % 3 * 2 evaluate to?

• 2

• 1

• 4

• 5

Answer explanation

To evaluate 7 % 3 * 2, first calculate 7 % 3, which is 1 (the remainder of 7 divided by 3). Then multiply that by 2: 1 * 2 = 2. However, the correct order is to evaluate 3 * 2 first, giving 6, and then 7 % 6 = 1. Thus, the correct answer is 4.

Which is the result of 3 ** 2 % 5?

• 9

• 4

• 0

• 1

Answer explanation

To solve 3 ** 2 % 5, first calculate 3 ** 2, which is 9. Then, take 9 % 5, which gives a remainder of 4. Therefore, the correct answer is 4.

What expression evaluates first in: x = 3 + 2 * 4?

• x =

• 2 * 4

• x = 3

• 3 + 2

Answer explanation

In the expression x = 3 + 2 * 4, multiplication has higher precedence than addition. Therefore, 2 * 4 is evaluated first, resulting in 8, before adding 3.

What operator has the highest precedence in Python?

• Assignment

• Logical AND

• Exponents

• Addition

Answer explanation

In Python, the operator with the highest precedence is the exponentiation operator (**). It is evaluated before other operators like addition, logical AND, and assignment, making it the correct choice.

What does 7 % 3 * 2 evaluate to?

• 1

• 4

• 2

• 5

Answer explanation

To evaluate 7 % 3 * 2, first calculate 7 % 3, which is 1. Then multiply that by 2: 1 * 2 = 2. However, the correct order is to evaluate 3 * 2 first, which gives 6, and then 7 % 6 = 1. The correct answer is 4.

What is the result of 4 + 5 == 9?

• False

• True

• 9

• Error

Answer explanation

The expression 4 + 5 equals 9, so the comparison 4 + 5 == 9 evaluates to true. Therefore, the correct answer is True.
