你这个里面有很多问题。。。。。。。对着看一下吧

userdata = {'111': '111'}


def newuser():
    name = input('what is your name:')
    while True:
        if name not in userdata.keys():
            key = input('please set a password:')
            print('successful,go for a try')
            userdata[name] = key
            return True
        else:
            name = input('this name has been used,please fill a new:')
            continue


def olduser():
    name = input('what is your name:')
    while True:
        if name not in userdata:
            name = input('this name do not find,please fill again:')
            continue
        else:
            key = input('please fill password:')
            while True:
                if key != userdata[name]:

                else:
                    print('welcome to system')
                    return True


flag = True
while flag:
    reminder = '''set new userdata(n/N)
