python date of the previous month

Question

I am trying to get the date of the previous month with python. Here is what i\'ve tried:

str( time.strftime(\'%Y\') ) + str( int(time.strftime(\'%m\'))-1 )
<         


        

Answer 1

For someone who got here and looking to get both the first and last day of the previous month:

from datetime import date, timedelta

last_day_of_prev_month = date.today().replace(day=1) - timedelta(days=1)

start_day_of_prev_month = date.today().replace(day=1) - timedelta(days=last_day_of_prev_month.day)

# For printing results
print("First day of prev month:", start_day_of_prev_month)
print("Last day of prev month:", last_day_of_prev_month)

Output:

First day of prev month: 2019-02-01
Last day of prev month: 2019-02-28
