#112035 — JSON result parsing

Calls to my REST api may either return a dict (for single results) or a list of dicts (for multiple results).

I receive these results using the requests library.

I want to retrieve the value for a key 'ID' but only if I have a single result and, obviously, if ID is present.

How can I do this with pythonic elegance?

Thanks for all suggestions!

    if len(results) == 1 and 'ID' in results:
        return results['ID']

    else:
        return 'something else'

I think John's answer missed this part.

If r is the result of the request, just testing

  if 'ID' in r: ... whatever ...

would do.  The result will be False if r is a list or the single result
does not have an ID.

Ah, that I leave to others.
