The Python documentation says:

 os.path.expanduser(path)

    On Unix and Windows, return the argument with an initial component
    of ~ or ~user replaced by that user‘s home directory.

    On Unix, 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.

This helps if HOME is not set.
