How to add seconds on a datetime value in Python?

Question

I tried modifying the second property, but didn't work.

Basically I wanna do:

datetime.now().second += 3

Answer 1

Have you checked out timedeltas?

from datetime import datetime, timedelta
x = datetime.now() + timedelta(seconds=3)
x += timedelta(seconds=3)

Answer 2

You cannot add seconds to a datetime object. From the docs:

A DateTime object should be considered immutable; all conversion and numeric operations return a new DateTime object rather than modify the current object.

You must create another datetime object, or use the product of the existing object and a timedelta.
