No worries… after all Python has strong Ada influences (it’s not by accident).
Sure, Python is everywhere. Just an example: if you have GNAT for Windows, there are no less than eight Python interpreters per GNAT version!

Yes!! That’s exactly the point.
Sometimes parsing input files from AOC puzzles is a bit tricky. Compared to other programming languages or libraries, the way the End_Of_File is signaled by Ada.Text_IO can cause the problem you mentioned. (e.g., in C++ eol() is returns true when you try to read pass the end, not after reading the last byte of the file)
Last year I had many problems parsing such files (and fell into the trap ;). At every puzzle I found easier ways to deal with this issue without repeating, once finished, the same logic that is performed inside the loop. For example, for me in day-1/part-1:
loop
declare
Line : String := Get_Line (Input);
begin
if Line'Length > 0 then
-- accumulate calories ...
end if;
if Line'Length = 0 or End_Of_File (Input) then
-- calories accumulated of one elf
-- compare with Max_Calories and get the max one
end if;
end;
exit when End_Of_File (Input);
end loop;
is the most simple and elegant way to process the file. I don’t like (and always avoid) repeating the same logic after the loop just because the way the file is read or the loop is structured.
