Intro to Python Exam 2 questions with
correct answers (3)
Sequences - correct answer ✔✔objects that can hold multiple items of data in order. You can then
perform operations on sequences to examine and manipulate the items stored in them.
What sequence types does Python use? - correct answer ✔✔Lists, tuples
Lists are mutable. What does this mean? - correct answer ✔✔Their contents can be changed during
program execution
What are the different ways lists can be created? - correct answer ✔✔[ ] with numbers and/or strings,
along with using range (list(range(2, 22, 2)))
What are Python's list operations? - correct answer ✔✔+ can join together two lists, * can repeat items
in lists, in keyword returns True if item is in list
What is the only way to change list items in a loop? - correct answer ✔✔By index
What numbers would you need in a range for 1-20? - correct answer ✔✔range(1,21)
How does slicing work in lists? - correct answer ✔✔To start from first index [:6]
To go to the end of the list [6:]
[-5:] can make the list count backwards
[:-5] will stop 5 items from end of the list
[1::2] will provide a step value, skipping every other value
What are the list methods? - correct answer ✔✔Append, insert, sort, del, index, min/max
