Pre-Pitch: Python 3.8.0a1 is available for Python developers

[Miro Hrončok]

Hi,

we now have a package with Python 3.8 first alpha. I'd like to spread the word.

tl;dr:

- dnf install python38  # or python3.8
  - as more alphas and betas are released upstream, the package gets updated
  - if you are a Python developer, test your project with tox on 3.8 early
    (don't wait for Fedora 31)
  - the (controversial) walrus operator is already available (:=)

Let me know if this makes sense for the magazine or if I shall bother social 
media list instead. Thanks.
