i am having trouble with creating a way to put lists into a existing one.. for example, i would like to make a input generate a list..

ex:
itens = []
itens.append(A)

i want this letter A to be placed into the list itens like this:

[[a]]

if i want to append a new letter it would generate a new list..

[[A], [B]]

is this even possible? it would be less complex to achieve what i need this way..

itens = []
add_itens = input("append me: ")
itens.append([add_itens])
print(itens)

A = 'a'
B = 'b'
items = []
items.append([A])
print(items)
items.append([B])
print(items)

Output:
[['a']]
[['a'], ['b']]

>>> items = list()
>>> items.append(['b'])        # append ['b'] to end of items
>>> items
[['b']]
>>> items.insert(0, ['a'])     # insert ['a'] at index 0 to items
>>> items
[['a'], ['b']]
