Finally installing Python3 on my new Mac so updated my family reconstitution code from Python 2 to 3 (very easy). Running both versions in test sequence produces identical results, core output and GEDCOM file. And the Python 3 runs 3 times faster than Python 2! This is reconstituting nearly 7000 baptisms and 3000 marriages at Melrose parish in Roxburghshire (Scottish Borders) before 1800. Putting children into families with parents, and outputting family groupings as a GEDCOM file for import into a genealogy program. This is the only Python program I've ever coded. I was a computer science PhD student when my neuro illness struck at age 22 in 1994. I had to drop out, and have barely coded since. But something must have stuck! The pseudo code was easy to convert into Python, even for a newbie.
