Tcl text processing: Python 3.10 variants

[Zhenfu Shi]

Hi all,

I’m trying to add Python 3.10 variant to a few ports, but one of them (mpv) uses `set python_branch [join [split ${ver} {}] ".”]` to convert branch strings to version strings, resulting in “310” being converted to “3.1.0”. Can anyone advise how to change this line so it gives “3.10” without breaking compatibility with older Python versions?

Thanks,
Zhenfu
