I am using requests module in my python program. It worked great in the previous day. But now, when importing requests module, it is showing a weird error. It is working great in python2 version. But shows error in python3. I googled it but can't find a solution. I haven't changed anything. Why it is showing this error.
Here it is:
>>> import requests

Reinstalling cryptography package will resolve this problem.

I think this is a Python issue. but I'm running Python3:
python -V shows
Python 3.9.0
I have installed it with homebrew.
What can be the problem?
This is a known issue across Mac, Windows and Linux: https://issuetracker.google.com/170125513.
I'd suggest to use the recommended Python versions mentioned here (3.5 to 3.8).
Also this does not affect only to Cloud SDK but others as well (for example as mentioned here).
Thanks for your answer. Indeed, it works with the version 3.8.6 of python.
I will add some infos if it can help somebody. In order to manage python version, I have used pyenv and installed the version of python I needed.
pyenv install 3.8.6
pyenv global 3.8.6
If you want a quick fix you can add this to your bash profile and restart your terminal:
export CLOUDSDK_PYTHON=python3.8
Worked for me

According to https://github.com/axnsan12/drf-yasg/issues/362#issuecomment-494360308, this problem might result from virtualenv not upgrading to the Python version you have installed.
Also, 3.7.4 has been released & includes changes related to Context Variables. Maybe upgrading to that helps?
There was a power outage in my area while i was working on a python script.After this happened, there was an error when i tried to import numpy.
ModuleNotFoundError: No module named '_ctypes'
In Pycharm,Project-> Settings ->Interpreter ,the package list is empty.
Also, pip install produces this error,

Everything was working as expected before this incident.What could have changed due to power outage?
How can i fix this this?
I saw a question very similar yours. Maybe it could help you:
importError: no module named _winreg python3
As it says in the _winreg documentation, it has been renamed to winreg in Python 3.0. You should run the 2to3 tool if you're converting code that was written for Python 2.x.
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
I have the most updated numpy, httplib2, pytz, Cython, python-dateutil & numexpr
And newest pandas build
But I'm flummoxed! The following code gives the following rather cryptic error. What is it trying to tell me?
import pandas
print "ok pandas"

Solution by furas and OP.
I had an old file called google.py. Just renamed/deleted it and problem was solved.
Probably python uses this file when it imports from google.appengine.api.
