get_opcode_module fails to detect 3-digit versions

[olafhering]

Unclear how it is supposed to work.
get_opcode_module fails to handle 3.6.12|3.8.6, and likely every 3.6.n|3.8.n.

Workaround is version_info[0:2] to find a match.

Unclear what the openSUSE Leap and Tumbleweed packages do wrong.

The traceback shows you are using uncompyle6 3.7.2.

Do yourself and me a favor and look up on and see what the latest version of uncompyle6 is. There are a number of ways to do this, but here is a link. In the Holiday/Christmas spirit, look at all of the red and green!

Also try this with xdis.

The reflect a minute: new versions of Python come out all of the time. Although it is a maintanance mess, we note that specific version numbers are associated with specific magic numbers. And we note those only for the Pythons that have really been released: If there is no such thing as a Python 3.8.100232 we don't purport to know anything about that.

You could imagine a different organization. And if you want to do the work to make it happen I'll entertain the idea, if it is viable.

This approach clashes with reality.

I have adjusted the openSUSE packages in the meantime.
