Hi!
I implemented a part of a script to subtract n months from datetime.
Basically I subtracted n%12 from year and n//12 from the month adding 12
months when it goes<=0. Then used try when converting to datetime again.
So, if the day is for example 31 for a 30 days month it raises a
ValuError exception. Then I subtract 1 to day and repeat.
The code seems too naive and very very complicated!
What is the best way to achieve this? Any existent module?
At the very end, what I want is to subtract nx where x can be y, m, w, d
for respectively years, months, weeks or days.
I feel I am missing something here ...
Thanks.
Paulo
