In http://docs.python.org/py3k/tutorial/interpreter.html#interactive-mode , the header shown is "Python 3.2 (py3k, Sep 12 2007, 12:21:02)". Python 3.2 was no made in Sep 12 2007, so it could not be compiled at that time.
It should be a correct date or the date of today.

Looks like the version got updated but not the rest, even the 3.3 doc has the same date.

The later lines also needs to be updated.

In http://docs.python.org/dev/tutorial/introduction.html, there is an ... line which is impossible in that case:

Variables must be “defined” (assigned a value) before they can be used, or an error will occur:

>>>
>>> # try to access an undefined variable
... n
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'n' is not defined

It should be:

>>> n # try to access an undefined variable
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'n' is not defined

Oops! The last message should be in a new issue.

I'm not sure it's worth updating it, it will probably get outdated again when new versions are released.  Also this is just an example, the actual header and dates might be different depending on the version/.OS/compiler.

Suggest closing: I think this causes no issue and changing it would have no benefit.

I don't mind fixing the year suggestion (in the interest of "realism" and for practice).

OK.  If you change the date also change s/py3k/default/, py3k was used on the SVN days.  Here is what my header looks like:

$ python3
Python 3.2.3 (default, May  3 2012, 15:54:42) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

While you are at it, you could also add .. code-block:: sh.

Fixed, and thanks for the report!

(Ezio, I didn't add "code-block:: sh" because it resulted in some undesired highlighting in the interpreter portion when I tried it.)
