Python Chapter 8 Questions and Answers Already Passed What is the simplest way to create a list of numbers from 1 to 5? Use `list(range(1, 6))`. How do you make a list contain the word "Python" five times? Use `["Python"] * 5`. What happens if you try to modify a tuple? Python raises a `TypeError` because tuples are immutable. How can you swap the first and last elements of a list? Use `list[0], list[-1] = list[-1], list[0]`. How do you create a list of the sq...
