Does anyone know how I can apply a date one day in the past as my filename? With this code, it would give me a file name of 'File09202021161235.csv' however I would like this to output 1 day in the past.

 'File'   datetime.datetime.today().strftime('%m%d%Y%H%M%S''.csv')

I tired using timedelta(days=1) but then the strftime breaks? Can anyone offer any guidance?

It's very simple. First of all you are doing it wrong.

datetime.timedelta(days=1)

It's only the time for 1 days. It's not a current time. It's an interval.

The fix is you need to subtract the this 1 days time interval from current time.

import datetime

#Here we are subtracting the current time with 1 days time interval
past_day = datetime.datetime.today() - datetime.timedelta(days=1)
your_file_name = 'File'   past_day.strftime('%m%d%Y%H%M%S''.csv')
