Python previous month with 2 digit

Question

I want 04 as output in premonth . Can some one help on this? tried diff format and no luck.

enter code here
premonth = str(int(time.strftime('%m'))-1)

tried using python date of the previous month but due to strftime restriction I am not able to proceed.

Answer 1

Not the best way but this should work:

a = str(int(time.strftime('%m'))-1)
a = '0'+a if len(a)==1 else a
