[Python-ideas] Re: Datetime operation in itertools count

I get your point. I checked the code which is in C and implement the solution which was something similar to yours. Should we have some function like that in the datetime module that can generate date, and time as well between two ranges? This looks like a feature to me that can be helpful. Yesterday I found Pandas Library has this feature https://pandas.pydata.org/docs/reference/api/pandas.date_range.html. What do you think? On Tue, Feb 8, 2022 at 9:23 PM Paul Moore wrote:

I wanted to generate all the dates between two date ranges for which I

For example

import datetime from itertools import count count(datetime.date.today(), datetime.timedelta(1))

Why is count function only limited to numbers shouldn't we make it

generic that it should support operation like datetime where addition between the objects is possible.

Because it's implemented in C for speed, and limiting it to numbers makes it both easier to implement (in C) and faster.

Would like to hear thoughts from you people.

start = date.datetime.today() (start + datetime.timedelta(n) for n in count())

does exactly the same as your code does, so it's not *that* hard to get the functionality you want already.
