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 Itse1359-1040-Strings Part 1 .

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.)

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 8

The escape sequence for the tab character is \t as shown in Figure 6 .

Figure 6 . The escape sequence for the tab character.
>>>print("\tTom\n\tDick, and\n\tHarry") TomDick, and Harry>>>

Go back to Question 8

Answer 7

Surround with single quotes, or use an escape character as shown in Figure 5 .

Figure 5 . Two ways to include double quote characters in a string.
>>>print('Richard "Dick" Baldwin') Richard "Dick" Baldwin>>>print("Richard \"Dick\" Baldwin") Richard "Dick" Baldwin>>>

Go back to Question 7

Answer 6

Escape sequences are special sequences of characters used to represent other characters that either

  • Cannot be entered directly into a string, or
  • Would cause a problem if entered directly into a string.

Examples are shown in Figure 4 .

Figure 4 . Example escape sequences.
>>>print(\ "She said, \"He \nwon't go\"")She said, "He won't go">>>

Go back to Question 6

Answer 5

Two representations are \012 and \n as shown in Figure 3 . Of the two, the latter is probably the most commonly used.

Figure 3 . Two representations of the newline character.
>>>print('Richard\012G.\nBaldwin') RichardG. Baldwin>>>

Go back to Question 5

Answer 4

The use of triple-quoted strings, as shown in Figure 2 , makes it possible for you to continue a string on a new line, and to preserve the line break in thestring.

Figure 2 . Triple-quoted strings.
>>>print("""Dick Baldwin""")Dick Baldwin>>>

Go back to Question 4

Answer 3

Surround the string with matching pairs of single quotes, double quotes, or triple quotes as shown in Figure 1 .

Figure 1 . Three ways to format string literals.
>>>print('Dick Baldwin') Dick Baldwin>>>print("Tom Jones") Tom Jones>>>print("""Mary Smith""") Mary Smith>>>

Go back to Question 3

Answer 2

Perhaps one way to describe the meaning of the word literal would be that the literal item is taken at face value, and its value is not subject tochange as the program executes.

Go back to Question 2

Answer 1

The common interpretation of the word string in computer programming is that a string is a sequence of characters that is treated as a unit. Forexample, a person's first and last names are often treated as two different strings.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
