python 3.7.3: Invalid syntax when importing spyne.

[pcs3rd]

Currently trying to use spyne. When trying to import it, python returns the following error:

Python 3.7.3 (default, Dec 20 2019, 18:57:59)

This is fixed with e9b1f3bb85d6 which is available in 2.13.3-alpha for the first time. Unfortunately, Python 3 support was never published in a stable release.

So, do I just have to install from the repository then or will this get built into a stable release build? And at that point, is the development branches extremely unstable if I use code from a few commits ahead of that one? And what about the spyne-flask module? Is that only python2?

[bgermann]

I would install the latest beta version from PyPI. I do not know anything about spyne-flask.

Thank you!
