Import error with named tuple and Mapping

Question

I have trying to fix an import error with the requests library in Python 3.11. This is to run a Discord bot that I have created. My original error is given as ImportError: cannot import name 'Mapping' from 'collections' and in response I have tried changing a line from from collections import namedtuple, Mapping to from collections.abc import namedtuple, Mapping. This has not fixed my original error. The new error created is the traceback given below:

ImportError: cannot import name 'namedtuple' from 'collections.abc' (C:\Users\andreas\AppData\Local\Programs\Python\Python311\Lib\collections\abc.py)

What's the original problem? Your attempted solution obviously isn't working since `collections.abc.namedtuple` doesn't exist. You can confirm that with the [docs](https://docs.python.org/3/library/collections.abc.html). — wjandrea, May 10 '23 at 19:12
@wjandrea My original problem is an import error with mapping. The error is as follows: `ImportError: cannot import name 'Mapping' from 'collections'` — mullena, May 10 '23 at 19:15

namedtuple is located in the collections module, Mapping -- in the collections.abc module. Starting from python 3.10 the line from collections import Mapping throws an error. You should separate the two imports, like so:

from collections.abc import Mapping
from collections import namedtuple

You must be using an outdated version of urllib3. This issue was fixed in Feb 2018 and then the selectors module was removed entirely, before version 1.23, released in Jun 2018.
