Is there a map without result in python?

Question

Sometimes, I just want to execute a function for a list of entries -- eg.:

for x in wowList:
   installWow(x, \'installed by me\')

Sometime

Answer 1

You might try this:

filter(lambda x: installWow(x, 'installed by me') and False, wowList)

That way, the return result is an empty list no matter what.

Or you could just drop the and False if you can force installWow() to always return False (or 0 or None or another expression that evaluates false).
