'NoneType'对象没有属性'count'

Question

我有一个错误，但我不知道为什么。这是我的代码：

import itertools
word = 'stop'
#input('Word [ 2-5 letters recommended ] :').lower()
word = list(str(word))
anagrams = ["".join(perm) for perm in itertools.permutations(word)]
file = open('wordlist.txt', 'r')
lines = file.read().split('n')
for n, i in enumerate(anagrams):
            if i not in lines:
                    anagrams[n] = '/'
for i in enumerate(anagrams):
    if '/' in anagrams:
        while anagrams.count('/') > 0:
            anagrams = anagrams.remove('/')
anagrams = 'n'.join(map(str,anagrams))
print(anagrams.strip(''))

这是错误：

Traceback (most recent call last):
  File "main.py", line 13, in <module>
    while anagrams.count('/') > 0:
AttributeError: 'NoneType' object has no attribute 'count'

我做错了什么吗？

Answer 1

刚刚想出了怎么做：

import itertools
word = input('Word [ 2-5 letters recommended ] :').lower()
word = list(str(word))
anagrams = ["".join(perm) for perm in itertools.permutations(word)]
file = open('wordlist.txt', 'r')
lines = file.read().split('n')
for n, i in enumerate(anagrams):
            if i not in lines:
                    anagrams[n] = '/'
if str('/') in anagrams:
    anagrams = [x for x in anagrams if x != '/']
anagrams = 'n'.join(map(str,anagrams))
print(anagrams)

输入：

Word [ 2-5 letters recommended ] : stop

输出：

stop
spot
tops
ostp
opts
post
pots
