This may be overkill and probably slow, but perhaps most in the spirit
that you're asking.
from itertools import chain
def r(x):
if x > 3:
raise(ValueError)
return x
def maybe(func):
try:
yield func()
except:
return
def p(i): return maybe(lambda: r(i))
your_list = list(chain(p(1), p(5)))
print your_list
