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 Itse1359-1070-Strings Part 2 .

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.)


Question 1 .

What is an ordinal number?

Go to answer 1

Question 2

What is indexing?

Go to answer 2

Question 3

True or False? We assign index values to the characters in a string.

Go to answer 3

Question 4

What is the syntax for accessing a character at a particular index in a string?

Go to answer 4

Question 5

What is the syntax for accessing a substring from a string using slicing?

Go to answer 5

Question 6

True or False? The second index of a slice is inclusive.

Go to answer 6

Question 7

What is the default value for the first index if you omit the first index value in a slice?

Go to answer 7

Question 8

What is the default value for the second index if you omit the second index value in a slice?

Go to answer 8

Question 9

What is the purpose of negative slice indices?

Go to answer 9

Question 10

What is the name and syntax of the function that can be used to find the length of a string?

Go to answer 10

What is the meaning of the following two images?

These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.

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 10

The function is named len . It requires one parameter, which is the name of the string as in:


Go back to Question 10

Answer 9

Negative indices can be used to count from the right end of the string toward the beginning of the string on the left.

Go back to Question 9

Answer 8

The default value is the length of the string (the actual number of characters in the string) , which is greater than the index of the last character in the string.

Go back to Question 8

Answer 7

The default value is zero (0).

Go back to Question 7

Answer 6

False. The character whose index value matches the second index of a slice is not included in the slice.

Go back to Question 6

Answer 5

Include both the start and stop index in square brackets, separated by a colon, as in aStr[10:16] .

Go back to Question 5

Answer 4

Refer to the string, and include the index value in square brackets, as in aStr[3] .

Go back to Question 4

Answer 3

False. Index values are automatically assigned to the characters in a string.

Go back to Question 3

Answer 2

Indexing is the process of assigning an ordinal index value to each data item contained in some sort of a container.

Go back to Question 2

Answer 1

An ordinal number is an adjective that describes the numerical position of an object, e.g., first, second, third, etc.
