7.1.8 - 7.1.9 Select Operators Quizizz Extra Practice (SD)

The operator that checks if two values are equal is (a)  

• ==

• =

• !=

• is

Answer explanation

The operator '==' checks if two values are equal. The '=' operator is used for assignment, '!=' checks for inequality, and 'is' checks for identity in Python. Therefore, '==' is the correct choice.

Which operator is used for assignment in Python?

• ==

• +=

• =

• !=

Answer explanation

In Python, the '=' operator is used for assignment, allowing you to assign a value to a variable. The other options ('==', '+=', '!=') serve different purposes, such as comparison or incrementing values.

What does the 'and' operator return if both conditions are True?

• True

• False

• None

• Error

Answer explanation

The 'and' operator returns True only if both conditions are True. Therefore, if both conditions are True, the correct answer is True.

Which of the following is a logical operator?

Which operator checks if a value exists in a list?

Which operator is used to find the remainder of a division?

The operator '//' is used to find the remainder of a division, also known as the modulus operator. The '/' operator performs standard division, not remainder calculation.

Which data type is returned by 5 / 2?

• int

• float

• str

• bool

Answer explanation

The expression 5 / 2 performs division, which in Python results in a float. Therefore, the correct answer is 'float', as it represents a number with a decimal point.

Which operator checks identity (same memory location)?

• ==

• is

• =

• in

Answer explanation

The 'is' operator checks for identity, meaning it verifies if two variables point to the same memory location. In contrast, '==' checks for value equality, while '=' is an assignment operator, and 'in' checks for membership in a collection.

What is the result of 10 > 5 and 3 == 3?

Answer explanation

The expression '10 > 5' is True and '3 == 3' is also True. The 'and' operator requires both conditions to be True, so the overall result is True.
