python - checking several variables against list of values

Question

I have a piece of code that needs to run if any of the variables match some strings. The code seems long and not very pythonic:

if candidate_job_title in ('ERROR', 'NOT AVAILABLE') or candidate_company in ('ERROR', 'NOT AVAILABLE') or candidate_location in ('ERROR', 'NOT AVAILABLE'):  
# do something

the best I could come up with is this, is there anything else I can do to make it more readable?

if any (v in ('ERROR', 'NOT AVAILABLE') for v in (candidate_job_title, candidate_company, candidate_location):
# do something

In your first code sample, you mentioned candidate_company twice. I think one of them should be candidate_location. — lllrnr101

Do all candidate properties need to be checked against the same set of strings? — lllrnr101

no, only a subset of all candidate properties need to be checked. — Patrick

No, I meant do you always need to check against ('ERROR', 'NOT AVAILABLE') only? Or can there be any other string for location and something else for company? — lllrnr101

If these values are hashable you can use set intersection:

if {candidate_job_title, candidate_company, candidate_location} & {'ERROR', 'NOT AVAILABLE'}:
