Spacer image of a rabbit and a penguin.

This image was also inserted for the purpose of inserting space between the questions and the answers.

Spacer image of a penguin and some houses.


Answer 12

A Python expression is evaluated by first evaluating each of the sub-expressions in the parentheses, and then using those values to complete theevaluation. If the expression contains nested parentheses, the evaluation is performed by evaluating the innermost parentheses first and working outwardsfrom there.

Go back to Question 12

Answer 11

Parentheses can be used to group terms in an expression in order to provide control over the order in which the operations are performed.

Go back to Question 11

Answer 10

False, the modulus operator is used to produce the remainder.

Go back to Question 10

Answer 9

False. Integer division produces an integer or whole number result with no non-zero digits to the right of the decimal point even if a decimal point isdisplayed.

Go back to Question 9

Answer 8

The operators and their purposes are:

  • The addition operator, +
  • The subtraction operator, -
  • The multiplication operator, *
  • The division operators, / and //
  • The modulus operator, %

Go back to Question 8

Answer 7

The plus sign is commonly called the operator. The 2 and the 5 are commonly called operands. More specifically, the 2 is the left operand and the 5 is theright operand.

True, unless the expression can't be evaluated, in which case an error message will appear.

Go back to Question 5

Answer 4


Go back to Question 4

Answer 3
