帮助，我创建了这个程序，因此它会生成一个包含您帐户详细信息的保存文件。但登录功能不起作用，我不知道什么是错的。即使用户名匹配，它仍然在incorect中说明

Answer 1

我认为这个块;

    file = open(user, 'r')
    if user == file:
        pasmatch = file.read(1)
        if pas == pasmatch:
            typer("Logging into your account...")

你的意思是：

    file = open(user, 'r')
    if pas == file.read(): #or maybe even if pas in file.read():
        typer("Logging into your account...")

没有详细说明，您的初始代码在等同事物方面存在一些问题（user == file没有任何意义，因为user是一个字符串而file是一个字符串fileObject）或你如何阅读（read(1)只读取一个字节）。

import sys
import time
import os
def typer(x):
    for i in x:
        print(i, end='')
        time.sleep(0.020)


def register():

    name = input('Create username: ')+'.txt'
    file = open(name, 'a')
    i = input("Create password: ")
    file.write(i+'\n')
    typer("Creating account...")

def login():
    user = input("Insert username: ")
    try:
        file = open((user+'.txt'), "r")  # line altered
    except FileNotFoundError:
        print("Username\Password incorrect")
        sys.exit()
    pas = input("Enter password: ")
    pas += '\n'  # line altered
    try:
        file = open((user+'.txt'), 'r')
        if (user+'.txt') == file.name:  # line altered
            pasmatch = file.read() # line altered, removed '1'
            if pas == pasmatch:
                typer("Logging into your account...")
    except:
        print("Username\Password i incorrect")
        sys.exit()



menu = True


while menu == True:
    menu = True
    print("What do you want to do?")
    print("1. Register")
    print("2. Login")
    ii = input("")
    if ii == "1":
        register()
    if ii == "2":
        login()
        menu = False

这应该这样做。我看到了使用文件对象作为文件名的问题。如果有帮助，请务必将此标记为解决方案。谢谢！
