How to convert a time string to seconds?

Question

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 s         


        

Answer 1

import time
from datetime import datetime

t1 = datetime.now().replace(microsecond=0)
time.sleep(3)
now = datetime.now().replace(microsecond=0)
print((now - t1).total_seconds())

result: 3.0
