Question O1: Python provides a wide variety of tools and programming techniques that you can
use to __ and __ strings.
A. examine; manipulate
B. delete; compile
C. import; print
D. index; tokenize
- answers 100%✔✔✔ 📌A
Rationale: Python includes many string methods for examining and manipulating text.

Question O2: Strings use ___ to access individual characters.
A. slicing
B. indexing
C. concatenation
D. tokenization
- answers 100%✔✔✔ 📌B
Rationale: Indexing uses bracket notation to access a character by position.

Question O3: In Python strings are __ meaning that the first character has index __, the second
has index __, and so on.
A. one-indexed; 1; 2
B. zero-indexed; 0; 1
C. negative-indexed; -1; 0
D. mutable; 0; 1

, - answers 100%✔✔✔ 📌B
Rationale: Python sequences are zero-indexed.

Question O4: When iterating through a string with a while loop in Python, the loop continues
until ___.
A. a sentinel value is found
B. the end of the string is reached
C. the index equals 1
D. the string becomes mutable
- answers 100%✔✔✔ 📌B
Rationale: The loop stops when the index reaches the length of the string.

Question O5: When iterating through a string with a while loop, you typically use ___ and ___
as the loop condition.
A. the length of the string; an index variable
B. split; join
C. class; object
D. startswith; endswith
- answers 100%✔✔✔ 📌A
Rationale: A common condition is index < len(string).

Question O6: For string concatenation, Python uses the augmented assignment operator __.
A. +=
B. -=
C. *=
D. /=
- answers 100%✔✔✔ 📌A
Rationale: += appends the right string to the left string variable.

Question O7: Strings are ___.
A. mutable
B. immutable
C. both mutable and immutable
D. neither
- answers 100%✔✔✔ 📌B
Rationale: Existing string characters cannot be changed in place.

,Question O8: String slices are called ___.
A. substrings
B. indexes
C. tokens
D. methods
- answers 100%✔✔✔ 📌A
Rationale: A substring is a contiguous slice of a string.

Question O9: The expression string[start:end] includes characters with ___, not including the
ending indexing position.
A. the starting indexing position up to the ending indexing position
B. only the ending position
C. all positions except the start
D. negative positions only
- answers 100%✔✔✔ 📌A
Rationale: Slicing includes the start index and excludes the end index.

Question O10: You can test to see if one string is contained in another string with the ___
operator.
A. in
B. is
C. ==
D. +
- answers 100%✔✔✔ 📌A
