in urllib.request.urlopen() is fixed to match the code.
The :mod:`urllib.request` module defines the following functions:
-.. function:: urlopen(url, data=None[, timeout], *, cafile=None, capath=None, cadefault=True)
+.. function:: urlopen(url, data=None[, timeout], *, cafile=None, capath=None, cadefault=False)
Open the URL *url*, which can be either a string or a
:class:`Request` object.
