英文:
Doesnt compare list's correctly
问题
def split(word):x = list(word)return xwhitelist = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P']word = input('Password ')split(word)x = split(word)if not all(letter in whitelist for letter in x):print('Incorrect letters')else:print('Correct')
英文:
def split(word):x = list(word)return xwhitelist = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']word = input('Password ')split(word)x = split(word)if x not in whitelist:print('Incorrect letters')else:print('Correct ')
When i enter FECHCH for eks. , 'if' keeps giving me communicate - inncorrect letters .
I need python3 to understand, that letters FECHCH are in whitelist.

您需要逐个输入字母
def split(word):x = list(word)return xwhitelist = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']word = input('密码 ')split(word)x = split(word)print(x)# 密码 FECHCH['F', 'E', 'C', 'H', 'C', 'H']
所以您正在比较：
['F', 'E', 'C', 'H', 'C', 'H'] 在 ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']
这是 False
正如评论中所提到的，您可以使用 set() 来去除重复并检查子集。
word = input('密码 ')split(word)x = split(word)if set(x).issubset(whitelist):print('正确 ')else:print('不正确的字母')
英文:
You need to enter letters one by one
def split(word):x = list(word)return xwhitelist = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']word = input('Password ')split(word)x = split(word)print(x)#Password FECHCH['F', 'E', 'C', 'H', 'C', 'H']
so you are comparing:
['F', 'E', 'C', 'H', 'C', 'H'] in ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']
which is False
as mentioned in comments, you can use a set() to remove duplicates and check subsets.
word = input('Password ')split(word)x = split(word)if set(x).issubset(whitelist):print('Correct ')else:print('Incorrect letters')

无需特殊的拆分函数。您可以简单地使用（假设您接受小写字母要被转换，否则省略upper()函数）：
whitelist = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P']word = input('密码 ')# 对每个字符进行报告for ch in word.upper():if ch not in whitelist:print('不正确的字母', ch)else:print('正确的字母', ch)# 或者检查整个单词for ch in word.upper():if ch not in whitelist:val = '不正确的字母'breakelse:val = '正确的字母'print(val)
英文:
No special split function is required. You could simply use (assuming you accept lower case letters to be converted else omit upper():
whitelist = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P']word = input('Password ')# to report on each characterfor ch in word.upper():if ch not in whitelist:print('Incorrect letter', ch)else:print('Correct letter', ch)# or to check the whole wordfor ch in word.upper():if ch not in whitelist:val = 'Incorrect letters'breakelse:val = 'correct letters'print(val)
