def post_account(self, headers=None, query=None, cdn=False, body=None):
return self.request(<EOL>'<STR_LIT:POST>', '<STR_LIT>', body or '<STR_LIT>', headers, query=query, cdn=cdn)<EOL>
POSTs the account and returns the results. This is usually
done to set X-Account-Meta-xxx headers. Note that any existing
X-Account-Meta-xxx headers will remain untouched. To remove an
X-Account-Meta-xxx header, send the header with an empty
string as its value.

:param headers: Additional headers to send with the request.
:param query: Set to a dict of query values to send on the
    query string of the request.
:param cdn: If set True, the CDN management interface will be
    used.
:param body: No known Swift POSTs take a body; but the option
    is there for the future.
:returns: A tuple of (status, reason, headers, contents).

    :status: is an int for the HTTP status code.
    :reason: is the str for the HTTP status (ex: "Ok").
    :headers: is a dict with all lowercase keys of the HTTP
        headers; if a header has multiple values, it will be a
        list.
    :contents: is the str for the HTTP body.
