Python - time difference in milliseconds not working for me

Question

I\'ve read a few posts about this and thought I had some code that worked. If the difference between the 2 values is less than a 1sec then the millisecs displayed is correct

Answer 1

The correct answer (in 2020) is:

>>> from datetime import timedelta
>>> timedelta(days=1, milliseconds=50) / timedelta(milliseconds=1)
86400050.0

The other answers lose precision and/or are more verbose.
