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 * 60) + d.minute) * 60) + d.second) / (60.0 * 60) 

Which gives 4.5 for 4:30am, 18.75 for 6:45pm, etc. Is there a better way?

Answer 1

h = d.hour + d.minute / 60. + d.second / 3600. 

has less brackets…
