Convert time (HH:MM:SS) to minutes in python

Question

How to convert HH:MM:SS to Minutes?

I tried below works fine:

  import datetime as DT
  t1 = DT.datetime.strptime('0:10:00', '%H:%M:%S')

I tried another example and getting error:

  import datetime as DT
  t1 = DT.datetime.strptime('9715:56:46', '%H:%M:%S')

Error:

  ValueError: time data '9715:56:46' does not match format '%H:%M:%S'

In this example it support Max 23 for %H, If my hours has more than 23(in this case i have 9715 hours) how to get it?

Answer 1

You can use sum with a generator expression or map:

from operator import mul

my_time = '9715:56:46'
factors = (60, 1, 1/60)

t1 = sum(i*j for i, j in zip(map(int, my_time.split(':')), factors))
t2 = sum(map(mul, map(int, my_time.split(':')), factors))

print(t1)  # 582956.7666666667

assert t1 == t2

Answer 2

datetime.datetime is a representation of a point in time, not a duration of time.

datetime.timedelta is a representation of a length of time. Observe:

from datetime import timedelta


delta = timedelta(hours=9715, minutes=56, seconds=46)
total_seconds = delta.total_seconds()
minutes = int(total_seconds // 60)
seconds = int(total_seconds % 60)

print('{minutes}:{seconds}'.format(minutes=minutes, seconds=seconds))

EDIT: I changed the code to work with python 2.7.
