Python issue with inheritence

I'm trying to check if a inherited class is an instance of it's superclass. But the inherited class and the super class are in separate files. I'm importing the inherited class with importlib as a dynamic import. So for example: python1.py:

class MySuperClass:
  pass

class MySuperClass:
  pass

python2.py:

from python1 import MySuperClass

class MyInheritedClass(MySuperClass):
  pass

from python1 import MySuperClass

class MyInheritedClass(MySuperClass):
  pass

python3.py:

import importlib
from python1 import MySuperClass

module = importlib.import_module('python2')
inheritedClass = getattr(module, 'MyInheritedClass')
if isinstance(inheritedClass, MySuperClass):
  print("MyInheritedClass is instance of MySuperClass")
else:
  print("MyInheritedClass isn't an instance of MySuperClass")

import importlib
from python1 import MySuperClass

module = importlib.import_module('python2')
inheritedClass = getattr(module, 'MyInheritedClass')
if isinstance(inheritedClass, MySuperClass):
  print("MyInheritedClass is instance of MySuperClass")
else:
  print("MyInheritedClass isn't an instance of MySuperClass")

This prints: MyInheritedClass isn't an instance of MySuperClass Does anyone know why that is the case?

How do I parse this using python and langchain's WebBaseLoader?

Hi, I'm trying to do the following: Create an or condition for SoupStrainer as bs_kwargs for WebBaseLoader where it will look for either a html tag, or a classname on all of the html tags. Currently I have only found a way to do an and condition, where it searches html tags with the classname. My code looks like this:

            current_url = 'https://example.org'
            # Create a SoupStrainer for <main> tags
            main_tag_strainer = SoupStrainer(name="main")

            # Create a SoupStrainer for elements with the class "entry-content"
            class_strainer = SoupStrainer(class_="entry-content")

            combined_strainer = main_tag_strainer | class_strainer

            loader = WebBaseLoader(
                web_paths=[current_url],
                bs_kwargs=dict(
                    parse_only=combined_strainer
                )
            )

            current_url = 'https://example.org'
            # Create a SoupStrainer for <main> tags
            main_tag_strainer = SoupStrainer(name="main")

            # Create a SoupStrainer for elements with the class "entry-content"
            class_strainer = SoupStrainer(class_="entry-content")

            combined_strainer = main_tag_strainer | class_strainer

            loader = WebBaseLoader(
                web_paths=[current_url],
                bs_kwargs=dict(
                    parse_only=combined_strainer
                )
            )

However, this causes the following error in my compiler:

unsupported operand type(s) for |: 'SoupStrainer' and 'SoupStrainer'

unsupported operand type(s) for |: 'SoupStrainer' and 'SoupStrainer'

I'm looking to combine 2 Soupstrainers into one without creating an and condition for the soupstrainer. I'm not quite sure if this is possible
