Hello, i am trying to learn Python and here is my problem:
In my program, i am trying to get the following result:
let say i have list of charachters E ['a','c',] and i have a N=3
As a result I should get (9 strings in total) -
aaa
aac
aca
caa
acc
cac
cca
ccc

My function bellow works, but it does not repeat the same char
it will print
ac
ca
need help, thanks

def comb(L1, n, L2=[]):
if not n: return pr(L2)
for i in range(len(L1)):
L2.append(L1.pop(i))
comb(L1, n-1, L2)
L1.insert(i, L2.pop())

Here's a string permutation in python that could reversed to solve your problem.
