Day11 作业在运行的时候遇到调用问题

  File "C:\Users\Administrator\Anaconda3\lib\site-packages\yagmail\sender.py", line 144, in send
    self.login()
  File "C:\Users\Administrator\Anaconda3\lib\site-packages\yagmail\sender.py", line 243, in login
    self._login(self.credentials)
  File "C:\Users\Administrator\Anaconda3\lib\site-packages\yagmail\sender.py", line 201, in _login
    self.smtp.login(self.user, password)
  File "C:\Users\Administrator\Anaconda3\lib\smtplib.py", line 730, in login
    raise last_exception
  File "C:\Users\Administrator\Anaconda3\lib\smtplib.py", line 721, in login
    initial_response_ok=initial_response_ok)
  File "C:\Users\Administrator\Anaconda3\lib\smtplib.py", line 642, in auth
    raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, b'Error: authentication failed')

我找到对应地文件，怎么修改呢。
144 self.login()
243 self._login(self.credentials)
。。。。

Start with the Day11 assignment and the traceback locations in yagmail/sender.py at lines 144 and 243. Reproduce the send attempt and inspect the SMTP login inputs and account configuration; done means the assignment sends mail without SMTPAuthenticationError 535.
