python - Python用户名和密码(Python Username and Password)

Question

I have to make a Landmark Credit Union in their online banking department.

(我必须在其网上银行部门中建立一个Landmark信用合作社。)

And so I'm trying to create a username and password verification/ creation program for the online service.

(因此，我正在尝试为在线服务创建用户名和密码验证/创建程序。)

Here is the problem:

(这是问题所在：)

When choosing a username and password, a client must enter a valid email address for their username (must contain an “@” symbol, must contain a “.”, and must contain a “.com” or “.edu”).

(在选择用户名和密码时，客户端必须为其用户名输入有效的电子邮件地址（必须包含“ @”符号，必须包含“。”，并且必须包含“ .com”或“ .edu”）。)

When choosing a valid password, the client must have ALL of the following: At least one (1) capital letter, be at least nine (9) characters long, and must contain one (1) special character.

(选择有效的密码时，客户端必须具有以下所有内容：至少一（1）个大写字母，至少九（9）个字符，并且必须包含一（1）个特殊字符。)

If a client enters an incorrect username, the program must respond with an appropriate message asking them to try again.

(如果客户端输入了错误的用户名，则程序必须以适当的消息作为响应，要求他们重试。)

If a client enters an incorrect password, the program must respond with an appropriate message asking them to try again.

(如果客户端输入了错误的密码，则程序必须以适当的消息作为响应，要求他们重试。)

Make a list of two usernames and passwords as an example of stored data that cannot be replicated, as they already belong to another client.

(列出两个用户名和密码，作为无法复制的存储数据的示例，因为它们已经属于另一个客户端。)

But I am having trouble containing the must-haves.

(但是我在包含必需品方面遇到了麻烦。)

File > Username.txt 'r' is:

(文件> Username.txt'r'为：)

Username 1 > CaptainMarvel25, Password 1 > AnythingisPossible25
Username 2 > Thor7, Password 2 > AllMightyThor7

but when I type the username it says define CaptainMarvel25.

(但是当我输入用户名时，它说定义CaptainMarvel25。)

help

(救命)

import csv

def main():
    with open("Usernames.txt","r") as file:
        file_reader = csv.reader(file)
        user_find(file_reader)
        file.close()

def user_find(file):
    user = input("Enter your username: ")
    for row in file:
        if row[0] == user:
            print("username found", user)
            user_found = [row[0],row[1]]
            pass_check(user_found)
            break
        else:
            print("not found")

def pass_check(user_found):
    user = input("enter your password: ")
    if user_found[1] == user:
        print("password match")
    else:
        print("password not match")
        user_find(file_reader)

main()

You'll need regex's to match your requirements, here is one way in Python to do that which I think will help you get started:

(您需要使用正则表达式来满足您的要求，这是Python中执行此操作的一种方法，我认为这将帮助您入门：)

# Pattern for special characters
pat = r'(?=.[!@#$%^&])' 

type(re.search(pat,'3fdssr2$3')) == re.Match                                                                                                                           
True

type(re.search(pat,'3fdssr223')) == re.Match                                                                                                                           
False

I hope this helps get you started.

Search the web for different regex patterns and you should find one for each of your cases.

(在网络上搜索不同的正则表达式模式，您应该为每种情况找到一个。)
