Creating a range of dates in Python

Question

I want to create a list of dates, starting with today, and going back an arbitrary number of days, say, in my example 100 days. Is there a better way to do it than this?

import datetime  a = datetime.datetime.today() numdays = 100 dateList = [] for x in range (0, numdays):     dateList.append(a - datetime.timedelta(days = x)) print dateList 

Answer 1

Marginally better...

base = datetime.datetime.today() date_list = [base - datetime.timedelta(days=x) for x in range(numdays)]
