path, all previous components (on Windows, including the previous drive letter,
if there was one) are thrown away, and joining continues. The return value is
the concatenation of *path1*, and optionally *path2*, etc., with exactly one
directory separator (``os.sep``) inserted between components, unless *path2* is
empty. Note that on Windows, since there is a current directory for each drive,
``os.path.join("c:", "foo")`` represents a path relative to the current
directory on drive :file:`C:` (:file:`c:foo`), not :file:`c:\\foo`.

(This means that an empty last part will result in a path that ends with a
separator.) Note that on Windows, since there is a current directory for
