In http://docs.python.org/py3k/tutorial/stdlib2.html#logging , some code in a code sample is missing ">>>".

The code is:

unsearched = deque([starting_node])
def breadth_first_search(unsearched):
    node = unsearched.popleft()
    for m in gen_moves(node):
        if is_goal(m):
            return m
        unsearched.append(m)


should be:
>>> unsearched = deque([starting_node])
>>> def breadth_first_search(unsearched):
>>>    node = unsearched.popleft()
>>>    for m in gen_moves(node):
>>>        if is_goal(m):
>>>            return m
>>>        unsearched.append(m)

Fixed, thanks for the report!

Thanks for the report.  Minor clarification for future reference.  Subsequent lines should begin with "..." (when doctest-style is used):

>>> def breadth_first_search(unsearched):
...     node = unsearched.popleft()
etc.

This issue still does not appear to be fixed - looking at http://hg.python.org/cpython/file/101354f95a07/Doc/tutorial/stdlib2.rst .

And sorry, the URL should be http://docs.python.org/py3k/tutorial/stdlib2.html#tools-for-working-with-lists.

The code didn't have any output, so I created a separate code block with regular Python highlight -- no need to add >>>/... there.
