Vous pouvez vous référer au nom du fichier pointé par le lien symbolique avec os.readlink ().
Je me demandais quelles fonctions sont dans le paquet os.
https://docs.python.org/3/library/os.html Bien que cela soit décrit dans, je voulais une liste de noms uniquement, j'ai donc recherché une implémentation qui affiche une liste de fonctions.

>>> import os
>>> help(os.access)
Help on built-in function access in module posix:
access(...)
access(path, mode) -> True if granted, False otherwise
Use the real uid/gid to test for access to a path. Note that most
operations will use the effective uid/gid, therefore this routine can
be used in a suid/sgid environment to test if the invoking user has the
specified access to the path. The mode argument can be F_OK to test
existence, or the inclusive-OR of R_OK, W_OK, and X_OK.
