I need a full explanation of Lists, and its commands similar to .append(), .extend(), pop() and the others.

I'll give it my best shot!

Append: Add an element to the end of a list.

fruits = ['banana', 'apple', 'pear', 'orange']
fruits.append('kiwi')

Our fruits list now looks like this: ['banana', 'apple', 'pear', 'orange', 'kiwi']

Delete (del): Remove an item from a list.

fruits = ['banana', 'apple', 'pear', 'orange']
del fruits[0];

Our fruits list now looks like this: ['apple', 'pear', 'orange']

Insert: Inserts an item into the list at a given index

fruits = ['banana', 'apple', 'pear', 'orange']
fruits.insert(1, 'kiwi')

Our fruits list now looks like this: ['banana', 'kiwi', 'apple', 'pear', 'orange']

Pop: Remove an item from a list at a given index (or the end if no index is given) The primary difference between this and del is that the value that is removed is returned

fruits = fruits = ['banana', 'apple', 'pear', 'orange']
x = fruits.pop(1);

Our fruits list now looks like this: ['banana', 'pear', 'orange'] and x is now equal to 'apple'

Extends: Also adds items to a list. The primary difference between this and append is that you can concatenate lists

fruits = ['banana', 'apple', 'pear', 'orange']
fruits2 = ['kiwi', 'lemon']
fruits.extend(fruits2)

Our fruits list now looks like this: ['banana', 'apple', 'pear', 'orange', 'kiwi', 'lemon']

I hope this helps! Let me know if I've missed any that you need explained.
