Is there a way to append elements to a list randomly, built in function

ex:

def random_append():
     lst = ['a']
     lst.append('b')
     lst.append('c')
     lst.append('d')
     lst.append('e')
     return print lst

this will out put ['a', 'b', 'c', 'd', 'e']

But I want it to add elements randomly and out put something like this: ['b', 'd', 'b', 'e', 'c']

And yes there's a function random.shuffle() but it shuffles a list at once which I don't require, I just want to perform random inserts only.
