实现用户输入用户名和密码,当用户名为 seven 或 alex 且 密码为 123 时,显示登陆成功,否则登陆失败,失败时允许重复输入三次
username = "seven" password = ‘123‘ user_inputname = input("请输入用户名：") user_inputpassword = input("请输入密码：") if user_inputname == username and user_inputpassword == password: print("登录成功！") else: print("登录失败！")
username = "seven" password = ‘123‘ count = 0 while count < 3: user_inputname = input("请输入用户名：") user_inputpassword = input("请输入密码：") if user_inputname == username and user_inputpassword == password: print("登录成功！") break else: print("登录失败！") count +=1
username = ["seven","alex"] password = ‘123‘ count = 0 while count < 3: user_inputname = input("请输入用户名：") user_inputpassword = input("请输入密码：") if user_inputname in username and user_inputpassword == password: print("登录成功！") break else: print("登录失败！") count +=1
