Shortcut OR-chain applied on list

Question

I\'d like to do something like this:

x = f(a[0]) or f(a[1]) or f(a[2]) or f(a[3]) or …

with a given list a and a given functio

Answer 1

I'm now using this:

x = next((v for v in (f(x) for x in a) if v), False)

It's a working idiom without doubling the call of f and without introducing a hacky local, but it still is not very readable (especially if x, f, a, and v are longer than one letter).

I'd be happy to hear of a better solution.

Answer 2

This should work:

next((x for y in a for x in (f(y),) if x),False)
