What would be the alternative? (assuming that you want to do the loop yourself)

new_results = []
for result in results:
    if result:
        new_results.append(result)
results = new_results

or else

for result in results:
    if not result:
        results.remove(result)

which doesn't do the exact same thing.
Honestly, this list comprehension is much faster to read and quite easy to understand.
I think we could rename the "result" variable "x" or "res" and it would be less confusing though.
