python - 从pylint了解 “Too many ancestors”

example.py:

'''
demo too many ancestors
'''
from flask_security.forms import RegisterForm
from wtforms.fields import TextField

class ExtendedRegisterForm(RegisterForm):
    '''An extended register form'''
    name = TextField('Name', [])

当我运行pylint时:

$ pylint -r n example.py
************* Module example
R:  7, 0: Too many ancestors (10/7) (too-many-ancestors)

这是什么意思，我该如何解决？

最佳答案

问题是您从一个拥有太多祖先的类继承:RegisterForm。在您的情况下，除了停止使用它(可能不是一种选择)之外，您无法对此做很多事情。因此，您可能要为此类禁用此消息，例如:

class ExtendedRegisterForm(RegisterForm): # pylint: disable=too-many-ancestors
