使用者輸入

import getpass    #調用python內建的庫username = input("username:")password = getpass.getpass("password:")print(username,password)    #輸入的密碼是暗文，在python中不能執行，在其他解譯器中可以_username = "itxpl"_password = "asd123"username = input("username:")password = input("password:")if _username == username and  _password == password: #加冒號     print("Welcome user {name} login...".format(name = username))  #自動縮排，強制，省掉了結束符，結構清晰else:     #和if是同級，所以不縮排      print("Invaid username or password!")  # 是子語句

 以上有個錯誤，

#輸入密碼是暗文，在pycharm中不能運行，不是python
