If by straightforward you mean one-liner, there is:
''.join(c for c in input_string if c not in string.printable)

If you care about performance though, string.translate is faster; as always, the best way to decide
on a performance issue is to profile the alternatives on your data and see if it's worth going for
the fastest one at the expense of readability.
