1. A list can contain elements of any data type, and the elements in a single list need not all be of the same type.
2.   The append() method adds a new element to the end of the list. Only one parameter is accepted.
3.   The extend() method takes only a list as an argument and adds each element of that parameter to the original list.

Example usage of append() :

> > > Mylist = [0, 1] 'ABC'

> > > mylist

[1, 2, 0, 'ABC']

> > > Mylist. Append (4)

> > > mylist

[1, 2, 0, 'ABC ', 4]

> > > Mylist. Append () 'haha'

> > > mylist

[1, 2, 0, 'ABC ', 4, 'haha']

> > >

Example of extend() usage:

> > > mylist

[1, 2, 0, 'ABC ', 4, 'haha']

> > > Mylist. The extend ([' lulu '])

> > > mylist

[1, 2, 0, 'ABC ', 4, 'haha', 'lulu']

> > > Mylist. The extend ([aaa, 'lalalala'])

Traceback (most recent call last):

> > > Mylist. The extend ([' 123123 ', 'lalalala'])

> > > mylist

[1, 2, 0, 'ABC', 4 'haha' 'lulu', '123123', 'lalalala]

> > > Mylist. The extend ([111111222])

> > > mylist

[1, 2, 0, 'ABC', 4 'haha', 'lulu', '123123', 'lalalala, 111111, 222]

> > >
