  1. import itertools
  2. print list(itertools.permutations(['a','d','e','g']))
  1. s = ['a', 'b', 'c']
  2. def permutation(s, i):
  3.     print(s)
  4.     if i == len(s):
  5.         print(s, i)
  6.     else:
  7.         for j in range(i, len(s)):
  8.             s[j], s[i] = s[i], s[j]
  9.             permutation(s, i + 1)
  10.             s[j], s[i] = s[i], s[j]
  11. permutation(s, 0)
