comment:3 Changed 3 years ago by aapitzsch

Usage of list in
zipped_coords = list(zip(*self)) in src/sage/combinat/tiling.py and in
Slist = list(zip([g.ideal() for g in C.gens()], C.invariants())) in src/sage/rings/number_field/number_field.py seems unnecessary.

In both cases, it is necessary, because one can use an iterator only once. And we need it twice.

Replying to chapoton:

Okay.
