[Qgis-user] Running QGis on a machine with Python 3.11 and PyCharm ?

[Zoltan Szecsei]

Hi Toussaint,
I am not a hard-core developer, but I script/code whenever I can 
automate a procedure, so:

  * It is my understanding that QGIS is developed/maintained in the QT
    environment - so go that way rather than PyCharm if you plan to
    dabble in QGIS development.
    Perhaps one of the devs that lurk on this user list will add to this
    comment of mine.
  * Get on to QGIS-dev as well - you might find some better guidance
    there, for PyCharm and other python scripting issues.

I will try to find time to set up QGIS and PyCharm on my laptop in the 
next day or so - *_but in the meantime, google_* "pycharm with qgis" - 
there are about a billion articles and videos that come up.

Oh!, Yes!, I am exaggerating..... :-)

Regards,
Zoltan
