What's the difference between the list methods append() and extend()?
append: Appends object at the end.
x = [1, 2, 3] x.append([4, 5]) print (x)
gives you: [1, 2, 3, [4, 5]]
extend: Extends list by appending elements from the iterable.
x = [1, 2, 3] x.extend([4, 5]) print (x)
gives you: [1, 2, 3, 4, 5]
