Are you matching the order to the obj_type?
objlist = [ (type_obj1, obj1a, obj2b),
(typ_obj2, obj2a, obj2b),
etc...]
objs = [type_of_obj1, type_of_obj2, etc...]
for n in range(len(objs)):
if objs[n] == objlist[n][0]:
objlist[n][1]()
else:
objlist[n][2]()
What significance does the order have?
You might be able to use a dictionary of tuples.
call_obj = {(type_obj1,0):obj1a,
(type_obj1,0):obj1b,
(type_boj2,1):obj2a,
(type_obj2,1):obj2b,
etc... }
call_obj[(type_of_obj,order)]()
