@@ -307,23 +307,29 @@ The :mod:`urllib.parse` module defines the following functions:
    ``b'a&\xef'``.
 
 
-.. function:: urlencode(query, doseq=False)
+.. function:: urlencode(query, doseq=False, safe='', encoding=None, errors=None)
 
-   Convert a mapping object or a sequence of two-element tuples  to a
-   "url-encoded" string, suitable to pass to :func:`urlopen` above as the
-   optional *data* argument.  This is useful to pass a dictionary of form
-   fields to a ``POST`` request.  The resulting string is a series of
-   ``key=value`` pairs separated by ``'&'`` characters, where both *key* and
-   *value* are quoted using :func:`quote_plus` above. When a sequence of
-   two-element tuples is used as the *query* argument, the first element of
-   each tuple is a key and the second is a value. The value element in itself
-   can be a sequence and in that case, if the optional parameter *doseq* is
-   evaluates to *True*, individual ``key=value`` pairs separated by ``'&'``are
-   generated for each element of the value sequence for the key.  The order of
-   parameters in the encoded string will match the order of parameter tuples in
-   the sequence. This module provides the functions :func:`parse_qs` and
-   :func:`parse_qsl` which are used to parse query strings into Python data
-   structures.
