A complex generator of a lot of dates.

Sometimes we need to generate a lot of datetime objects and at this moment we have not a good solution for this, so I suggest something like this:

import random

from datetime import datetime, timedelta



def bulk_create_datetimes(date_start, date_end, **kwargs):
    """Bulk create datetime objects

    :param date_start: Begin of the range.
    :param date_end: End of the range.
    :param kwargs: Keyword arguments for datetime.timedelta
    :return: List of datetime objects
    """

    dt_objects = []

    assert date_start and date_end

    while date_start <= date_end:
        date_start += timedelta(**kwargs)
        dt_objects.append(date_start)

    return dt_objects

How it works:

>>> week_ago = datetime.now() - timedelta(days=7)
>>> now = datetime.now()
>>> datetimes = bulk_create_datetimes(week_ago, now, minutes=60)
>>> for i in datetimes:
....    print(i)

Result:

2018-08-21 12:58:55.687991
2018-08-21 13:58:55.687991
2018-08-21 14:58:55.687991
2018-08-21 15:58:55.687991
2018-08-21 16:58:55.687991
...
2018-08-28 12:58:55.687991

So, I think that it’s pretty simple to understand and there is no need for comments.

That gives extreme flexibility in generating dates because a user can generate dates with any difference between them (including seconds, minutes and etc.).

Why not both? We can have two methods that do A and B.
