How can I get hours from a Python datetime?

Question

I have a Python datetime, d, and I want to get the number of hours since midnight as a floating point number. The best I\'ve come up with is:

h = ((((d.hour         


        

Answer 1

h = (d - d.replace(hour=0,minute=0,second=0)).seconds / 3600.

... has less division and/or multiplication
