pros and cons between os.path.exists vs os.path.isdir

I'm checking to see if a directory exists, but I noticed I'm using os.path.exists instead of os.path.isdir. Both work just fine, but I'm curious as to what the advantages are for using isdir instead of exists.

os.path.exists will also return True if there's a regular file with that name.

os.path.isdir will only return True if that path exists and is a directory, or a symbolic link to a directory.

Just like it sounds like: if the path exists, but is a file and not a directory, isdir will return False. Meanwhile, exists will return True in both cases.

os.path.isdir() checks if the path exists and is a directory and returns TRUE for the case.

Similarly, os.path.isfile() checks if the path exists and is a file and returns TRUE for the case.

And, os.path.exists() checks if the path exists and doesn’t care if the path points to a file or a directory and returns TRUE in either of the cases.
