Answers

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>>>

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.
