"." and ".." are explicitly ignored by os.listdir() an os.scandir().

IMO the specific function os.walk() is not a good example. It includes
symlinks to directories in the dirs list and then it does not follow
symlink, it is a recursive function and has a followlinks optional
parameter (default: False).

Moreover, in 92% of cases, functions using os.listdir() and
os.path.isdir() *follow* symlinks:
