True

After a function finishes executing, control returns to the place the function was called.

False

An assignment statement affects a program's flow of control.

False

An if statement cannot have both an elif and an else clause.

False

An if statement is used to process the user's thoughts on the meaning of life.

True

If A and B are both false, then the expression A and B is false.

True

If A is false, then the B operand in the expression A and B is not evaluated.

False, B must also be evaluated.

If A is false, then the B operand in the expression A or B is not evaluated.

True

If the user input indicates that the likelihood of rain is 'certain', it will be treated as a negative response.

True

In Python, the relational operators can be used to put character strings in alphabetical order.

Age, from string to integer so it can be treated as a number.

In the conversation program, which input value was converted to another type after being entered by the user?

height = 15, size = 10, width = 110

Of the options given, what values of the variables height, size, and width would cause the following code to set the variable weight to 100? if height < size: weight = 50 if width < 20: print('short') else: if width > 100: weight = 100 println('tall')

True

Python comments begin with a hash mark (#) and extend to the end of the line.

False

The arithmetic operators have a lower precedence than the relational operators.

Input

The data needed by an algorithm to accomplish its task.

Output

The data produced by an algorithm.

True

The differences in case are ignored when processing the user's favorite band.

False
