This limitation is easy to remove, and the list comprehension a the
same time (OTOH, it relies on lists having a __getitem__):
def unwrap(list):
return list[0]
def list_to_dict(aList, key_indexes, value_indexes):
if len(key_indexes) > 1:
k = tuple
else:
k = unwrap
if len(value_indexes) > 1:
v = tuple
else:
v = unwrap
res = {}
for a in aList:
f = a.__getitem__
res[k(map(f,key_indexes))] = v(map(f,value_indexes))
return res
