Exclude 'None' from list comprehension of dicts

Hi,
I am constructing a list of dictionaries via the following list
comprehension:
data = [get_job_efficiency_dict(job_id) for job_id in job_ids]
However,
get_job_efficiency_dict(job_id)
uses 'subprocess.Popen' to run an external program and this can fail.
In this case, the dict should just be omitted from 'data'.
I can have 'get_job_efficiency_dict' return 'None' and then run
filtered_data = list(filter(None, data))
but is there a more elegant way?
Cheers,
Loris
