How to convert a time string to seconds?

I need to convert time value strings given in the following format to seconds, for example: 1.'00:00:00,000' -> 0 seconds 2.'00:00:10,000' -> 10 seconds 3.'00:01:04,000' -> 64 seconds 4.'01:01:09,000' -> 3669 seconds Do I need to use regex to do this? I tried to use the time module, but time.strptime('00:00:00,000','%I:%M:%S') throws: ValueError: time data '00:00:00,000' does not match format '%I:%M:%S' Edit: Looks like this: from datetime import datetime pt = datetime.strptime(timestring,'%H:%M:%S,%f') total_seconds = pt.second + pt.minute*60 + pt.hour*3600 gives the correct result. I was just using the wrong module.
import datetime import time x = time.strptime('00:01:00,000'.split(',')[0],'%H:%M:%S') datetime.timedelta(hours=x.tm_hour,minutes=x.tm_min,seconds=x.tm_sec).total_seconds() 60.0
