[Tutor] formatting datetime.timedelta to "HH:MM:SS"

[Jignesh Sutar]

Thanks folks, I think I have this as a working solution:

import datetime, time
a= datetime.datetime.now()
time.sleep(7.1564651443644)
b= datetime.datetime.now()
#for testing longer time periods
#a= datetime.datetime(2003, 8, 4, 8, 31, 4,0)
#b= datetime.datetime(2004, 8, 5, 19, 32, 6,0)
c = b-a
print "%s days, %.2dh: %.2dm: %.2ds" %
(c.days,c.seconds//3600,(c.seconds//60)%60, c.seconds%60)

The attributes for timedelta seem only to be days, seconds and microseconds
only. Nonetheless these can be used to deduce HH:MM:SS.

Thanks,
Jignesh
