Question

因此，该程序可以正常运行，并与名为用户名和密码的文本文件一起运行。但是，当文本文件中包含用户名和密码时，我不太知道如何停止使用任何密码的用户名，因为我只希望用户名与密码在同一行上使用。

import random
Empty = []
userfile = open("username.txt","r")
print("Welcome to my custom made game, please login so we know your a verified user.")
def readData(): #Load the files and log in
        Empty = []
        for each_line in myfile:
                Empty.append(each_line)
        print(Empty)
#myfile = []
#for line in userfile:
   #     myfile.append(line)

#readData()
def password():
        myfile = open("username.txt","r")
        passw = input("Please enter the password:")
        for line in myfile:
                eachline=line.split(",")
                if eachline[0].strip() and eachline[1].strip() == passw:
                        print("Valid password")
                        break
        else:
                print("Incorrect please try again")
                password()

def username():
        myfile = open("username.txt","r")
        user = input("Please enter the username:")
        for line in myfile:
                eachline=line.split(",")
                if eachline[0] == user:
                        print("Valid username")
                        password()
                        break
        else:
                print("Incorrect please try again")
                username()
username()

#password()
