Initialize List with Range in Python

Introduction

In Python, you can create a list of numbers using the range() function. However, sometimes you may want to create a list of numbers that are not sequential or that start at a different number than 0. In such cases, you can use the initialize_list_with_range() function.

Initialize List with Range

Write a function initialize_list_with_range(end, start=0, step=1) that initializes a list containing the numbers in the specified range where start and end are inclusive with their common difference step.

The function should return a list of the appropriate length, filled with the desired values in the given range.

Input

end (integer) - The end of the range (inclusive).
start (integer, optional) - The start of the range (inclusive). Default is 0.
step (integer, optional) - The common difference between each number in the range. Default is 1.

Output

A list containing the numbers in the specified range.

def initialize_list_with_range(end, start = 0, step = 1):
  return list(range(start, end + 1, step))

initialize_list_with_range(5) ## [0, 1, 2, 3, 4, 5]
initialize_list_with_range(7, 3) ## [3, 4, 5, 6, 7]
initialize_list_with_range(9, 0, 2) ## [0, 2, 4, 6, 8]

Summary

In this challenge, you learned how to create a list of numbers using the initialize_list_with_range() function. This function allows you to create a list of numbers that are not sequential or that start at a different number than 0.
