Subtracting a Day from a Date in Python

Determining the best approach to subtract a day from a given Python datetime object is a common programming challenge. Here, we delve into a reliable method using a timedelta object:

from datetime import datetime, timedelta

days_to_subtract = 1  # Replace with the desired number of days
d = datetime.today() - timedelta(days=days_to_subtract)

This operation creates a timedelta object representing the number of days to subtract and then subtracts it from the datetime object d. The resulting variable d will contain the adjusted date that is one day fewer than the original date.
