Chapter 7.3, Problem 13CP
Program Plan Intro
List slicing:
- • Slicing is a concept of selecting a range of elements from a list.
- • In Python, an expression that selects a subsection of a list is known as a slice.
- • A slice is a span of elements that are taken from a list.
- • Normally, the slice expression has a start index and an end index for slicing.
- • Negative integers can also be used as indexes in the slicing expressions. The negative indexes refer to location relative to the end of the list.
Syntax:
In Python, the list slice statement with a negative index can be expressed as either.
listname[negativeIndex:]
or
listname[:negativeIndex]
Explanation:
In the list slice syntax,
- • As the “start” index or the “end” index is the negative index, Python adds this negative index with the length of the list to get the start or end reference position for slicing.

- Return Growing NumList This function will be given a single number, it should return a list of strings of numbers. Each string in the list will only contain a single number repeated an arbitrary amount of times. The number each string will contain will be equal to the current string's index+1. The number in the string should be repeated the same number of times as the string's index+1. Each number in the string should be separated by a space. This list should stop when its size equals the max number specified.
