Hello
I think that my problem is linked to the data struture that I'm using for
the dates since my error message is : "ValueError: setting an array element
with a sequence."
I use list data structure, the one that you can declare through :
datetime_list = [].
And maybe I souldn't use this type of data structure and another one.
Regards
Johan Mazel
