python的几个实例程序员节日快乐

python的几个小实例

• 有参函数

  def login(username, password):
  
      name = input("请输入您的姓名").strip()
      pwd = input("请输入您的密码").strip()
      if name == username and pwd == password:
          print("登录成功")
      else:
          print("登录失败")
  username = 'zhanyafeng'
  password = '123456'
  
  login(username, password)
  

• 七段数码管数字
