1list.append(x)
2#Add an item to the end of the list. Equivalent to a[len(a):] = [x].
3
4list.extend(iterable)
5#Extend the list by appending all the items from the iterable. Equivalent to a[len(a):] = iterable.
6
7list.insert(i, x)
8#Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a), x) is equivalent to a.append(x).
9
10list.remove(x)
11#Remove the first item from the list whose value is equal to x. It raises a ValueError if there is no such item.
12
13list.pop([i])
14#Remove the item at the given position in the list, and return it. If no index is specified, a.pop() removes and returns the last item in the list.
