最佳答案
这可以使用itertools完成
from itertools import permutations
def perm(word):
perms = [''.join(p) for p in permutations(word)]
print(perms)
return perms
def capPer(arrPerm):
result=[]
for val in arrPerm:
wordList=list(val)
for i,letter in enumerate(wordList):
wordList[i]=letter.upper()
result.extend(perm(''.join(wordList)))
return set(result)
def combi(wrd):
print(capPer(perm(wrd)))
combi('ab')
combi('dan')
**output:**
set(['aB', 'Ba', 'BA', 'Ab', 'AB', 'bA'])
set(['aND', 'ANd', 'Dna', 'naD', 'DaN', 'aDn', 'Adn', 'dnA', 'NdA', 'anD', 'DnA', 'NAD', 'nAD', 'Dan', 'NDA', 'nAd', 'AdN', 'DAn', 'AnD', 'And', 'DNA', 'daN', 'adN', 'nDa', 'dAN', 'dNa', 'aDN', 'ADN', 'dNA', 'Nda', 'AND', 'DNa', 'NaD', 'Nad', 'aNd', 'nDA', 'dAn', 'NAd', 'ndA', 'NDa', 'ADn', 'DAN'])
