Subject: Use specific Python version to run shapes.py
X-Git-Tag: 2.44.1~79^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=09250ca96c7ca7574f2721ad5d233a9690cb69e7;p=graphviz

Use specific Python version to run shapes.py

The script runs fine with both Python 2 and Python 3, but on
e.g. Fedora 31, Centos 8 & Ubuntu 20.04 there is no "python"
program. Only "python2" and "python3".

For some rationale regarding Centos 8, see
