需要或使用哪些功能来升级我的代码？

Question

我正在尝试使用if-else-elif函数创建一个简单的用户名/密码编码，我需要一些建议

Username = input("Please Enter your Username " )

if Username == 'Angela':

    print('Hello Angela')

elif Username != 'Angela':


 print('The Username' , Username , 'is not registered!')

Password = input("Please Enter Your Password ")

if Password == 'Chair':

    print('You are now logged in')

elif Password != 'Chair':

    print('Wrong Password')
