Question

in a string suppose 12345 , i want to take nested loops , so that i would be able to iterate through the string in this following way :-

1. 1, 2, 3, 4, 5 would be taken as integers
2. 12, 3, 4,5 as integers
3. 1, 23, 4, 5 as integers
4. 1, 2, 34, 5 as integers
   …

And so on. I know what’s the logic but being a noob in Python, I’m not able to form the loop.

Answer 1

You can do the inner traversals by following code, the first traversal is trivial.

s = '12345'

chars = [c for c in s]

for i in range(len(s) - 1):
    print '%d:' % i,
    for el in chars[:i] + [chars[i] + chars[i + 1]] + chars[i + 2:]:
        print el,
    print
