Ciao, Angelo.

From ​https://docs.python.org/2/c-api/string.html:

These functions have been renamed to PyBytes_* in Python 3.x. Unless otherwise noted, the PyBytes functions available in 3.x are aliased to their PyString_* equivalents to help porting.

​https://docs.python.org/3/c-api/bytes.html

And this has been fixed recently in version 6:

• ​https://github.com/root-mirror/root/commit/555c71e2a199af80d5ddf3ab372b43525ec63255

We need to ask the upstream developers if they plan to support Python3 in ROOT 5.

• ​https://sft.its.cern.ch/jira/browse/ROOT-6485

[cjones051073 (Chris Jones)]

Thanks for the report. Until fixed upstream I suggest as a work around switching to one of the python 2.X variants, which stills works fine.

[mojca (Mojca Miklavec)]

Upstream claims to have fixed the issue.

I'm not sure if it's just ​https://github.com/root-mirror/root/commit/fb258576e9f7971305df1a4bcf3dea8d76bcaadd or also something else.

I'm not (yet?) maintainer of ROOT5. Ryan probably got it wrong. I happily leave the testing to maintainers, but since no maintainer has commit rights anyway, I'll commit the patch once I get the confirmation that it's ok (probably no need for a revbump).
