为什么它显示组合对象而不是组合我想打印所有长度的所有可能组合

问题描述

我想将可能的组合打印为所有长度的字符串

import itertools

string = input()

l1 = [ ]

for i in string:
    l1.append(i)

combo = []

combo = [itertools.combinations(l1,i) for i in range(len(l1))]  #i want to resolve this line

print(combo)

解决方法

试试这个

import itertools
string = input()
l1 = [i for i in string ]

combo = [list(itertools.combinations(l1,i)) for i in range(len(l1))] 
print(combo)
