Question

I have a simple for loop followed by a simple if statement:

for airport in airports:
    if airport.is_important:

and I was wondering if I can write this as a single line somehow.

Yes, I can do this:

for airport in (airport for airport in airports if airport.is_important):

but it reads so silly and redundant (for airport in airport for airport in airports...).

Is there a better way?

Answer 1

No, there is no shorter way. Usually, you will even break it into two lines :

important_airports = (airport for airport in airports if airport.is_important)
for airport in important_airports:
    # do stuff

This is more flexible, easier to read and still don’t consume much memory.
