这包含一些更高级的概念,但应该很容易遵循：
import string
def long_enough(pw):
'Password must be at least 6 characters'
return len(pw) >= 6
def short_enough(pw):
'Password cannot be more than 12 characters'
return len(pw) <= 12
def has_lowercase(pw):
'Password must contain a lowercase letter'
return len(set(string.ascii_lowercase).intersection(pw)) > 0
def has_uppercase(pw):
'Password must contain an uppercase letter'
return len(set(string.ascii_uppercase).intersection(pw)) > 0
def has_numeric(pw):
'Password must contain a digit'
return len(set(string.digits).intersection(pw)) > 0
def has_special(pw):
'Password must contain a special character'
return len(set(string.punctuation).intersection(pw)) > 0
def test_password(pw, tests=[long_enough, short_enough, has_lowercase, has_uppercase, has_numeric, has_special]):
for test in tests:
if not test(pw):
print(test.__doc__)
return False
return True
def main():
pw = input('Please enter a test password:')
if test_password(pw):
print('That is a good password!')
if __name__=="__main__":
main()
