I’d like to know if it is possible to install the development headers for Python 3.8 alpha.
Hello @batisteo! Welcome to the community! Please do take a few minutes to go over the introductory posts in #start-here when you have the time. They contain lots of useful information.
I’m not a Python expert (no, I’m not an expert at all 
), with development headers you mean a package like foo-devel?
Yes, exactly!
I know Python 3.8 is only in alpha right now, and that’s awesome that in the repo already!
My issue is I’d like to know if my project is future-proof, and some of the dependencies need to be compiled (lxml, asyncpg…) so it would need the python3-devel for Python 3.8 alpha 4+.
It doesn’t seems available.
You may need to track the upstream changes manually, especially for alpha releases. Python in general is an integral part of the Fedora Workstation offering, and most Linux distro’s it would seem, so the odds are in your favour but not guaranteed for certain.
python38 includes the headers which you can use to build those things.
