Just a simple generalization to the great response of taskinoor

In the context of my problem the format is similar, but includes AM or PM.

Format 'HH:MM:SS AM' or 'HH:MM:SS PM'

For this case the function changes to:

def get_sec(time_str):
"""Get Seconds from time."""
if 'AM' in time_str:
    time_str = time_str.strip('AM')
    h, m, s = time_str.split(':')
    seconds = int(h) * 3600 + int(m) * 60 + int(s)
if 'PM' in time_str:
    time_str = time_str.strip('PM')
    h, m, s = time_str.split(':')
    seconds = (12 + int(h)) * 3600 + int(m) * 60 + int(s)

return seconds
