When I look at wikipedia, it says about GNAT Studio:
GPS supports a variety of programming languages other than Ada, including C, JavaScript, Pascal and Python.
But when I look at the AdaCore site, I can't seem to find the necessary guidance to adapt GNAT Studio into a python development environment.
To answer the question, yes I am aware of IDLE and have used it. I have no further comment to say about that.
Yes, that is possible.
You can find the user manual of GNAT Studio here:
https://docs.adacore.com/live/wave/gps/html/gps_ug/index.html
There is also a section about supported languages:
https://docs.adacore.com/live/wave/gps/html/gps_ug/projects.html#supported-languages
On that page you can read, that for the languages Ada, C, C++ GNAT Studio has advanced support, but other languages can be added. There is also a link to a page where it is explained how to add languages support:
https://docs.adacore.com/live/wave/gps/html/gps_ug/extending.html#adding-support-for-new-languages
But you should think thoroughly if it is worth the effort. GNAT Studio is mostly produced and maintained by one company only (AdaCore). There is a risk that they decide to discontinue GNAT Studio. AdaCore over the last years shows ambitions to support also Visual Studio Code (e.g. https://marketplace.visualstudio.com/items?itemName=AdaCore.ada and https://docs.adacore.com/spark2014-docs/html/ug/en/source/how_to_run_gnatprove.html#running-gnatprove-from-visual-studio-code). It may be unclear if they really see a business case for two IDEs. The Open Source community for Ada is most likely too small to take over the development of GNAT Studio in case AdaCore decides to stop the investment in it.
