THE OUTPUT
WORKING WITH LISTS AND MANIPULATING THEM
Original list: ['one', 'two', 'three']
After changing numbers[3] the list became: ['one', 'two', 'change three']
After appending 'four': ['one', 'two', 'change three', 'append four']
After inserting five: ['one', 'two', 'change three', 'append four', 'insert five']
insert zero at the beginning: ['insert zero', 'one', 'two', 'change three', 'append four', 'insert five']
Remove 'insert zero': ['one', 'two', 'change three', 'append four', 'insert five']
The popped item is: insert five
Popped the last item: ['one', 'two', 'change three', 'append four']
We have popped: one
After popping one: ['two', 'change three', 'append four']
After removing two: ['change three', 'append four']
