Single line for loop over iterator with an “if” filter?

Question

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

for airport in airports:
    if airport.is_important:

and

Answer 1

I found the usage of the filter & lambda to be the easiest in a single line.

for filtered_airport in filter(lambda airport: airport.is_important, airports)):
    print(filtered_airport.some_property)

If you wish to return a list from output of this filter object you can do something like this.

filtered_airport_list = list(filter(lambda airport: airport.is_important, airports)))
