How to convert an H:MM:SS time string to seconds in Python?

Community

Basically I have the inverse of this problem: Python Time Seconds to h:m:s

I have a string in the format H:MM:SS (always 2 digits for minutes and seconds), and I need the integer number of seconds that it represents. How can I do this in python?

For example:

  • “1:23:45” would produce an output of 5025
  • “0:04:15” would produce an output of 255
  • “0:00:25” would produce an output of 25

etc

def get_sec(time_str):
    """Get seconds from time."""
    h, m, s = time_str.split(':')
    return int(h) * 3600 + int(m) * 60 + int(s)


print(get_sec('1:23:45'))
print(get_sec('0:04:15'))
print(get_sec('0:00:25'))
