## Python has a set of built-in methods that you can use on lists.
append() # Adds an element at the end of the list
clear() # Removes all the elements from the list
copy() # Returns a copy of the list
count() # Returns the number of elements with the specified value
extend() # Add the elements of a list (or any iterable), to the end of the current list
index() # Returns the index of the first element with the specified value
insert() # Adds an element at the specified position
pop() # Removes the element at the specified position
remove() # Removes the item with the specified value
reverse() # Reverses the order of the list
sort() # Sorts the list
## Happy coding :)
