TRUE/FALSE
1. You cannot use a for loop to iterate over the characters in a string.
ANS: F
2. Indexing works with both strings and lists.
ANS: T
3. In slicing, if the end index specifies a position beyond the end of the string, Python will use the length
of the string instead.
ANS: T
4. 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.
ANS: F
5. The index -1 identifies the last character of a string.
ANS: T
6. The following expression is valid:
string[i] = 'i'
ANS: F
7. The following code will display 'yes + no':
mystr = 'yes'
yourstr = 'no'
mystr += yourstr
print(mystr)
ANS: F
8. If the + operator is used on strings, it produces a string that is a combination of the two strings used as
its operands.
ANS: T
9. When accessing each character in a string, such as for copying purposes, you would typically use a
while loop.
