Clean the list

Instructions

Create a file clean_the_list.py that contains a function clean_list which takes and returns a list of strings and performs the following operations on each list item:

• Removes all spaces before and after (but not between words).

• Capitalizes the first letter (first letter only, other ones should be to lowercase).

• Adds its index number before a separator x/ .

• An empty list as input should return an empty list as output.

• And don't forget the milk! (add it at the end of the list if missing).

Usage

Here is an example of how to use the clean_list function:

import clean_the_list
shopping_list = ['tomatoes', 'pastas', 'milk', 'salt']
print(clean_the_list.clean_list(shopping_list))

This will output:

$ python test.py
['1/ Tomatoes', '2/ Pastas', '3/ Milk', '4/ Salt']
$
