Subtracting days from variable in date and time-CodePudding

I need to subtract 1 day from the current date and time? How would i do that? Here is my code:

from datetime import datetime
now = datetime.now()
date = (now.strftime("%Y-%m-%d %H:%M:%S"))
print(date)

Say the date is (2021-10-3) i need the time variable to be set to something like (2021-10-2) Changing the day by -1 day!

CodePudding user response：

Use timedelta.

from datetime import datetime, timedelta
now = datetime.now()
yesterday = now - timedelta(days=1)
date = (yesterday.strftime("%Y-%m-%d %H:%M:%S"))
print(date)
