# cat user.txt

# vim r1.py
#!/bin/python3
# -*- coding: utf-8 -*-

name=True
while name:
    inp_username=input('you name:').strip()
    inp_password=input('you password:').strip()
    with open('user.txt',mode='rt',encoding='utf-8') as f:
        for line in f:
            username,password=line.strip().split(':')

            if inp_username == username and inp_password == password:
                print('login successfull')
                name=False
                break
        else:
            print('username or password error')

# python3 r1.py
