TypeError: test_1_login() takes 1 positional argument but 2 were given怎么解决

Question

 def login(self,username,password):
        self.visit()
        self.input_(self.user,username)
        self.input_(self.pwd,password)
        self.click(self.login_button)

python
  @file_data('../Data/user.yaml')
    def test_1_login(self,**kwargs):
        self.lp.login(kwargs['username'],kwargs['password'])
        sleep(3)

Answer 1

Test_1_login()这个函数接受1个位置参数，但给出了2个。参数不对应所以报了错
