Python: Fix issues using PyCharm and Docker

If you try to run a Docker container from within PyCharm, and you get something like:

Couldn't refresh skeletons for remote interpreter
...

or:

can't open file '/opt/.pycharm_helpers/pycharm/django_test_manage.py'
...

Then you should clear all pycharm helpers from your docker containers and images:

docker ps -a | grep -i pycharm | awk '{print $1}' | xargs docker rm
docker images | grep -i pycharm | awk '{print $3}' | xargs docker rmi

Another useful troubleshooting tip for Docker-related errors is to select File > Invalidate Caches... within PyCharm, and then restart the app.
