when importing web3 in python getting error

I am trying to execute the "import web3" statement in python console and getting the following error.
EDIT: I am using Python 3.9.0a1 and pip 21.3.1.
I have tried doing it both in VSCode terminal and windows command prompt.
>>> import web3

You mentioned no version numbers.
https://stackoverflow.com/help/minimal-reproducible-example
I installed these from conda-forge, with interpreter 3.9.7 on MacOS 12.0.1:
typing-extensions 4.0.1
web3 5.26.0
And then import web3 works Just Fine.

TypeError from importing discord.py

I just installed the discord.py rewrite branch, but attempting to use import discord or from discord.ext import commands simply results in a TypeError.

Although the error is technically from yarl rather than from discord.py itself, the error only occurs upon trying to import the modules.
I've already tried reinstalling python as well as the discord.py rewrite branch, and if it makes any difference am running on a RPi 3 B+

Your aiohttp package might be out of date.
Try
pip install --upgrade aiohttp

I tried to install discord.py on my python 3.7 and it didn't work.
I had to install python 3.6.6 to make it work, maybe you are using python 3.7, if so you should try rolling back to python 3.6.6

On windows there is no sudo command. You have to run the command line as administrator and run the pip commands from above without sudo.

you can try this commands to fix it:
pip uninstall requests
pip install --upgrade requests

Tweepy installation?

I tried to install tweepy by using different methods such as
pip install tweepy
sudo pip install tweepy
Lastly, i downloaded zip package from the github and used the command to install:
python setup.py install
Apparently, installation was completed successfully, however when i run a simple program which contains only one line such as import tweepy, the following error is thrown:

AttributeError: 'module' object has no attribute 'maketrans'

You should try
pip3 install tweepy
or...
pip install git+https://github.com/tweepy/tweepy.git

Based on what you are saying. I assume you are using python3. You can have a work-around to make this work by replacing this File
File
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/textwrap.py on line 82
From
whitespace_trans = string.maketrans(
to
whitespace_trans = str.maketrans(
This would make the code compile for python3 docs.

There is another installation option you could try that clones a repo from GitHub:
git clone https://github.com/tweepy/tweepy.git
cd tweepy
pip install .

Python error while installing using homebrew

Hi I installed python using "homebrew install python".
A script which was already running started throwing below error.

Any Idea why this happened?
Python version is Python 2.7.6
