.. function:: urlencode(query, doseq=False, safe='', encoding=None, errors=None)
Convert a mapping object or a sequence of two-element tuples, which may
either be a :class:`str` or a :class:`bytes`, to a "percent-encoded"
contain :class:`str` or :class:`bytes` objects, to a "percent-encoded"
string. If the resultant string is to be used as a *data* for POST
operation with :func:`~urllib.request.urlopen` function, then it should be
properly encoded to bytes, otherwise it would result in a :exc:`TypeError`.

the value sequence for the key. The order of parameters in the encoded
string will match the order of parameter tuples in the sequence.
When *query* parameter is a :class:`str`, the *safe*, *encoding* and *error*
parameters are passed down to :func:`quote_plus` for encoding.
The *safe*, *encoding*, and *errors* parameters are passed down to
:func:`quote_plus` (the *encoding* and *errors* parameters are only passed
when a query element is a :class:`str`).
To reverse this encoding process, :func:`parse_qs` and :func:`parse_qsl` are
provided in this module to parse query strings into Python data structures.
