如何生成范围内所有可能排列的列表

Question

I would like to generate words list in a specific way. I would like to find all permutations for my variable l='EDCMI' not only for 5 characters but for 4 characters, 3 characters etc.

Answer 1

Just use a nested for loop and remember to add 1 to your range argument to include permutations the same length as your input string:

from itertools import permutations

s = 'EDCMI'

for i in range(len(s) + 1):
    for p in permutations(s, i):
        print(''.join(p))
