'Ln.'

-1

What are the valid indexes for the string 'New York'? a. 0 through 7 b. 0 through 8 c. -1 through -8 d. -1 through 6

0 through 7

An expression of the form string[i] = 'i' is a valid expression.

False

Indexing of a string starts at 1, so the index of the first character is 1, the index of the second character is 2, and so forth.

False

The strip() method returns a copy of the string with all leading whitespace characters removed, but does not remove trailing whitespace characters.

False

When accessing each character in a string, such as for copying purposes, you would typically use a while loop.

False

What is the return value of the string method lstrip()? a. The string with all whitespace removed b. The string with all leading spaces removed c. The string with all leading tabs removed d. The string with all leading whitespaces removed

The string with all leading whitespaces removed

If a whole paragraph is included in a single string, the split() method can be used to obtain a list of the sentences included in the paragraph.

True

If the + operator is used on strings, it produces a string that is the combination of the two strings used as its operands.

True

In slicing, if the end index specifies a position beyond the end of the string, Python will use the length of the string instead.

True

Indexing works with both strings and lists.

True

Invalid indexes do not cause slicing expressions to raise an exception.

True

The index - 1 identifies the last character in a string.

True

Which list will be referenced by the variable list_strip after the execution of the following code? list_string = '03/07/2008' list_strip = list_string.split('/') a. ['3', '7', '2008'] b. ['03', '07', '2008'] c. ['3', '/', '7', '/', '2008'] d. ['03', '/', '07', '/', '2008']

['03', '07', '2008']

Which method would you use to determine whether a substring is the suffix of a string? a. endswith(substring) b. find(substring) c. replace(string, substring) d. startswith(substring)

endswith(substring)

Which method would you use to determine whether a substring is present in a string? a. endswith(substring) b. find(substring) c. replace(string, substring) d. startswith(substring)

find(substring)

If the start index is_____the end index, the slicing expression will return an empty string. a. equal to b. less than c. greater than d. not equal to

greater than

Which of the following string methods can be used to determine if a string contains only '\n' characters? a. ischar() b. isalpha() c. istab() d. isspace()

isspace()
