Python datetime minus 1 day using timedelta

Question

I would like the first datetime in the hyperlink to be 1 day before the second which is today's date. I read a little bit about the timedelta but I did not see how it applied within a hyperlink.

Answer 1

Some well placed parentheses should suffice:

(datetime.datetime.now() - datetime.timedelta(days=1)).strftime('%Y-%m-%d')

A friendly suggestion: take a look at Python string formatting instead of constructing your string using concatenation. It'll end up being a lot cleaner and less repetitive.
