Time signatures are crap. They should have switched to a number
over a note value a long time ago; we could have easily avoided
abominable travesties like the time signature on the 2nd
movement of Beethoven's 9th (B needed four over dotted quarter). If
music notation had been invented by a computer scientist we
wouldn't be stuck in the current mess in which 6/8 means two
completely different meters (3 over quarter, or 2 over dotted
quarter).

And... er... Python doesn't need a time signature data type. But
rationals would be quite nifty. ;-)
