This module is one in a collection of modules on Python designed for teaching ITSE 1359 Introduction to Scripting Languages: Python at Austin Community College in Austin, TX.

This module contains review questions and answers keyed to the module titled Itse1359-1020-Numbers .

Once you study that module, you should be able to answer the review questions in this module.

The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

(Note to blind and visually impaired students: with the exception of two bitmap images that are used solely as spacers to separate the question sectionfrom the answer section, all of the material in this module is presented in plain text format and should be accessible using an audio screen reader or abraille display.)

Answers

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.

Go back to Question 7

Answer 6

False. Just the reverse is true. Programs are made up of statements, which are composed of expressions.

Go back to Question 6

Answer 5

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

Go back to Question 5

Answer 4

True.

Go back to Question 4

Answer 3

False. The Python interactive system also uses a secondary prompt consisting of three periods (...).

Go back to Question 3

Answer 2

False. In Python, a comment starts with the hash character (#) and ends at the end of the line.

Go back to Question 2
