15 years later, it seems asyncio subprocesses may have the same issue. :)

Justin Lebar added the comment:
Ah, I see. The examples do what you think they should do, but not for the
reason you think they should do it -- the JSON encoding logic calls the
encoder's encode() method before calling its default() method.
I still think the examples could be improved
New submission from Justin Lebar:
The JSONEncoder documentation says we can implement our own encoder as:
class ComplexEncoder(json.JSONEncoder):
... def default(self, obj):
... if isinstance(obj, complex):
... return [obj.real, obj.imag]
... return

The readline documentation currently says:
readline.insert_text(string)
Insert text into the command line.
But as far as I can tell, readline.insert_text() does something only when
called from startup_hook or pre_input_hook
Justin Lebar justin.le...@gmail.com added the comment:
Actually, maybe startup_hook doesn't do what it sounds like it does and
insert_text() only works from startup_hook.
If this is the case, then the documentation for startup_hook could also be
improved:
The startup_hook function is called

The documentation for assertTrue/assert_/failUnless reads:
assertTrue(expr, msg=None)
assert_(expr, msg=None)
failUnless(expr, msg=None)
...
Deprecated since version 3.1: failUnless().
The deprecation warning is confusing, since
Justin Lebar star...@gmail.com added the comment:
Oh, I see.
I still think a complete sentence would be helpful here, although now that I
understand that the colon doesn't mean use instead I suppose I'm less
confused...

Many programmers are used to languages where the RNG is deterministic unless
it's explicitly seeded. This does not appear to be the case in Python.
The documentation for random should indicate that Random objects are seeded on
construction
Justin Lebar star...@gmail.com added the comment:
Ack. I read it twice looking for that line!
Perhaps it should still indicate that new Random objects are automatically
seeded. And perhaps the line I missed should be a little bit louder?

It's not at all clear from the documentation that base64.base64encode() and its
kin return bytes, rather than strings. Since this matters now, the docs should
be clear on this point.

At http://docs.python.org/3.1/library/itertools.html,
For instance, SML provides a tabulation tool: tabulate(f) which produces a
sequence f(0), f(1), But, this effect can be achieved in Python by
combining map() and count() to form map
