Most of the time, it is the same.
But, path can exist physically whereas path.exists()
returns False. This is the case if os.stat() returns False for this file.
If path exists physically, then path.isdir()
will always return True. This does not depend on platform.
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.
os.path.exists(path) Returns True if path refers to an existing path. An existing path can be regular files (http://en.wikipedia.org/wiki/Unix_file_types#Regular_file), but also special files (e.g. a directory). So in essence this function returns true if the path provided exists in the filesystem in whatever form (notwithstanding a few exceptions such as broken symlinks).
os.path.isdir(path) in turn will only return true when the path points 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.
