Wohl wahr... Nicht sch=F6n, aber quasi-funktional ist vielleicht =
Folgendes:


In [1]: def do(item): print(item)

In [2]: def empty(): print('no luck')

In [3]: _ =3D len([do(item) for item in [1, 2, 3]]) or empty()
1
2
3

In [4]: _ =3D len([do(item) for item in []]) or empty()
no luck


Die Zuweisung nur, damit es keine Ausgabe gibt...
