在列表、输入中寻找东西

Question

我目前正在 Python 3.3.2 上制作密码检查器，我目前正在通过执行以下操作在用户输入中查找内容：

if ("A" in PassCheck) or ("B" in PassCheck) or ("C" in PassCheck) or ("D")in 
PassCheck) or ("E" in PassCheck) or ("F" in PassCheck) or ("G" in PassCheck) 
or ("H" in PassCheck) or ("I" in PassCheck) or ("J" in PassCheck) or ("K" in 
PassCheck) or ("L" in PassCheck) or ("M" in PassCheck) or ("N" in PassCheck 
 or
("O" in PassCheck) or ("P" in PassCheck) or ("Q" in PassCheck) or ("R" in 
PassCheck) or ("S" in PassCheck) or ("T" in PassCheck) or ("U" in PassCheck)
or ("V" in PassCheck) or ("W" in PassCheck) or ("X" in PassCheck) or ("Y" in 
PassCheck) or ("Z" in PassCheck):

有没有办法通过列表来做到这一点？

Answer 1

您可以使用string 库通过string.ascii_uppercase 模块搜索是否存在大写字符

>>> import string
>>> string.ascii_uppercase
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

然后您可以使用any 函数来测试给定字符串输入是否存在大写字符。

>>> Pass_Check_1 = 'ThisOneWorks'
>>> any(i in Pass_Check_1 for i in string.ascii_uppercase)
True

>>> Pass_Check_2 = 'thisonedoesntwork'
>>> any(i in Pass_Check_2 for i in string.ascii_uppercase)
False
