Question

问题：是否可以分配＆＃39;传递＆＃39;变量的关键字？如果不可能请解释我为什么？

def validate_password(first_pwd, second_pwd):

    vowels = [a,e,i,o,u]
    first_length = len(first_pwd)
    second_length = len(second_pwd)
    passed_test = pass   #<----- This bit here#
    # pwd length
    # is password length over 8 characters?
    if first_length >= 8:
        passed_test
    else:
        print("Password too short")
        # are the passwords the same
        if first_pwd == second_pwd:
            passed_test
        else:
            print("Password Mismatch")
            # are the passwords first and last character different
            if first_pwd[0] != first_pwd[-1]:
                passed_test
            else:
                print("First Charater cannot be same as the last character")





# CODE TESTING AREA #
password1 = "abcd1234"
password2 = "abcd1234"
print(validate_password(password1, password2))

^ Return False ^ invalid password

password1 = "Abcd1234"
password2 = "Abcd1234"
print(validate_password(password1, password2))

^ Return True ^ Valid Password

password1 = "Abedi23a"
password2 = "Abedi23a"
print(validate_password(password1, password2))

^ Return False ^ invalid password

Psudo Code

如果无法通过＆＃39; Pass＆＃39;在变量ill里面只需留下评论，告诉我它做了什么

Answer 1

不，你不能 - pass是一个陈述，而不是一个价值。好像您想将return分配给变量。

话虽如此，为什么你甚至想要分配一个基本上意味着nothing或ignore的陈述？如果您不想要执行某些操作，请不要首先调用它：

def validate_password(first_pwd, second_pwd):

    vowels = [a,e,i,o,u]
    first_length = len(first_pwd)
    second_length = len(second_pwd)

    # pwd length
    if first_length < 8:
        print("Password too short")
    elif first_pwd != second_pwd:
        print("Password Mismatch")
    elif first_pwd[0] == first_pwd[-1]:
        print("First Charater cannot be same as the last character")
    elif first_pwd[0].isalpha(vowels) != first_pwd[-1].isalpha(vowels):
        # this is incomplete code there is a bunch that follow but i didnt put in here#
        pass
    else:
        print("All is good!")
        return True
    return False

pass是Python中的保留关键字。它不能直接分配给任何变量。为了更有意义，你可以简单地为它指定无

passed_test=None
for x in range(2):
    passed_test

在元音中，文字应该用引号括起来。

str.isalpha（）方法检查字符串是否仅由字母字符组成

import re
def validate_password(first_pwd, second_pwd):
    first_length = len(first_pwd)
    second_length = len(second_pwd)
    tmp=first_pwd.lower()
    # pass = pass   #<----- This bit here#
    # pwd length
    if first_length < 8:
        print("Password too short")
    elif first_pwd != second_pwd:
        print("Password Mismatch")
    elif tmp[0].isalpha() and tmp[-1].isalpha() and \
        tmp[0] == tmp[-1]:
        print("First Charater cannot be same as the last character")
    elif len(re.findall('[aeiou]',tmp))>2:
        print("More than 2 vowels")
    elif not re.search(r'[a-z]',tmp):   
        print("No alphabetic character")
    elif first_pwd in (first_pwd.upper(),tmp):
        print("All Characters are in same case")
    else:
        return True
    return False

我可以分配＆＃34;通过＆＃34;变量/名称的关键字？
