Generator comprehensions return generator in single assignment variable, but in multiple assignment it doesn’t return generators.
# generator comprehension gen = ((x for x in [1, 2, 3])) gen >><generator object <genexpr> at 0x7f92b4e33500> # returns not generator but each lists # if assign multiple variables lst1, lst2 = ((x for x in ([1, 2, 3],[4, 5, 6]))) lst1 >>[1, 2, 3] lst2 >>[4, 5, 6]
