os.supports_effective_ids

os.supports_effective_ids

A Set object indicating which functions in the os module permit use of the effective_ids parameter for os.access(). If the local platform supports it, the collection will contain os.access(), otherwise it will be empty.

To check whether you can use the effective_ids parameter for os.access(), use the in operator on supports_effective_ids, like so:

os.access in os.supports_effective_ids

Currently effective_ids only works on Unix platforms; it does not work on Windows.
