List Methods in Python
What is a List?
Lists are collections of data that are surrounded by brackets [ ] and each item in the list is separated by commas.
What can be in a list?
Strings, numbers, booleans, even other lists can be items in a list. Lists are ordered and mutable (changeable). This means that lists can be sorted and changed. The way we can change lists is through list methods.
