Bad Code Snippet of the Day

[Chris Angelico]

I call this "Russian Exception Roulette". It came about because of
some discussions on python-ideas regarding the new PEP 463 and
exception handling.

try:
    exc = getattr(__builtins__,random.choice(list(filter(lambda x:
x.endswith("Error"),dir(__builtins__)))))
    f()
except exc:
    print("You win!")


Given a function f(), defined elsewhere, what will this do?

Note that this was developed on Python 3.4, and some of the details
may be different on other versions (especially 2.x).
