I have this function:
def function(start_date_arrow=None,end_date_arrow=None, date_concept=None):
list=[getattr(date, date_concept) for date in arrow.Arrow.range(date_concept, start_date_arrow, end_date_arrow)]
This function works well when iterating over date_concept='month' and date_concept='day'. On the other hand, date_concept='year' only returns a list of one item.
For example:
start_date_arrow= arrow.get('2021-11-05')
end_date_arrow= arrow.get('2022-02-05')
year_list=function(start_date_arrow=start_date_arrow,end_date_arrow=end_date_arrow, date_concept='year')
year_list is [2021]
month_list=function(start_date_arrow=start_date_arrow,end_date_arrow=end_date_arrow, date_concept='month')
month_list is [11, 12, 1, 2]
day_list=function(start_date_arrow=start_date_arrow,end_date_arrow=end_date_arrow, date_concept='day')
day_list is [5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]
Second and third call are okei, but first one should return [2021,2022] instead of [2021].
Any idea of what is happening in the year call?
Found the issue. If you use:
start_date_arrow= arrow.get('2021-11-05')
end_date_arrow= arrow.get('2022-02-05')
Year difference between both is less than 1, so it only returns the first one, so to return 2022 in the list end_date_arrow should be end_date_arrow= arrow.get('2022-11-05')
So I forced with an if statement the end date to be bigger just by one year, to force the return of both years.
