What is the difference between os.path.basename() and os.path.dirname()?

What is the difference between os.path.basename() and os.path.dirname()? I already searched for answers and read some links, but didn't understand. Can anyone give a simple explanation?
Both functions use the os.path.split(path) function to split the pathname path into a pair; (head, tail). The os.path.dirname(path) function returns the head of the path. E.g.: The dirname of '/foo/bar/item' is '/foo/bar'. The os.path.basename(path) function returns the tail of the path. E.g.: The basename of '/foo/bar/item' returns 'item' From: http://docs.python.org/3/library/os.path.html#os.path.basename
