Here's the description of os.path.expanduser from the docs[1]:

expanduser(path)

  On Unix, return the argument with an initial component of "~" or
  "~user" replaced by that user's home directory. An initial "~" is
  replaced by the environment variable HOME if it is set; otherwise
  the current user's home directory is looked up in the password
  directory through the built-in module pwd. An initial "~user" is
  looked up directly in the password directory.

  On Windows, only "~" is supported; it is replaced by the environment
  variable HOME or by a combination of HOMEDRIVE and HOMEPATH.

  If the expansion fails or if the path does not begin with a tilde,
  the path is returned unchanged.
