TypeError：check（）缺少1个必需的位置参数：'self'

我尝试使用re来创建一个代码来将我的邮件存储在一个文件中，并在启动时检查它是否在该文件中其他人请求我再次键入它

我试过把'self'放在第28行的函数名之前（错误）

import re

class login(object):

def check(self):
    self.mail = r"([\w\.-]+)@([\w\.-]+)([\w\.-]+)"
    with open('login.txt', 'r') as self.myfile:
        self.line1 = self.myfile.read().replace('\n', '')
    with open('username.txt', 'r') as self.usr:
        self.line2 = self.usr.read().replace('\n', '')
    if re.findall(self.mail, self.line1):
        goon()
    else:
        log()
    self.myfile.close()

def goon(self):
    import assistant #another code to exec.

def log(self):
    self.file = open("login.txt", "w")
    self.file.truncate(0)
    self.data = input("Your email: ")
    self.file.write(self.data)
    self.file.close()
    l.goon()

if __name__ == '__main__':
    check() #error
    log()
    goon()
