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?

Answer 1

You can also use the day ordinal to make it simpler:

def date_range(start_date, end_date):
    for ordinal in range(start_date.toordinal(), end_date.toordinal()):
        yield datetime.date.fromordinal(ordinal)

Or as suggested in the comments you can create a list like this:

date_range = [
    datetime.date.fromordinal(ordinal) 
    for ordinal in range(
        start_date.toordinal(),
        end_date.toordinal(),
    )
]
