PyCharm-Community has been backported from Cauldron.
Uploaded to core/backports_testing
Mageia 6, x86_64
Installed the packages and launched the Pycharm IDE to get an idea of how it worked.
Back on this tomorrow with a simple python project, hopefully.
Continued investigating the Pycharm interface and tried the virtual environment option. Set it up and then abandoned it because I did not really know what I was doing
Managed to find a reasonably complex program to code, an ASCII art converter for images, found in a Python ebook. Used emacs outside the IDE to edit the code, to speed things up, and then imported it into Pycharm for testing. Edited it in the interface to get rid of a couple of errors and ran it in the built in terminal emulator to generate an ASCII art text file which could be viewed in a normal terminal using 'cat'. That is as far as I go with this. There is obviously a lot more to using it than this sketchy outline but it certainly works OK for a newbie.
