The most basic login script in Python

import getpass

_username = 'wu'
_password = 'wu123'
username = input("username:")
#password = getpass.getpass("password:") #密文输入
password = input("password:")

if _username == username and _password == password:
    print("Welcon user {name} login... ".format(name=username))  #直接花括号定义了一个name变量？
else:
    print("Invalid username or password!")

#print(username,password)
