I had also tried such tests. If you pass a single argument msg, it is
assigned to the message property, and the args property is set to
(msg,). If you pass more than one argument, the tuple of arguments is
assigned to the args property, and nothing is assigned to the message
property. I was hoping to at least find source code that provides a
definitive answer.

TOPIC: can pydoc display doc for local funcs? or other doc tools for own code

From: News123

Hi,

often I start "pydoc -g" in a projects working directory in order to
view the docstrings of my own project and in order to get a quick
overview of the code structure

In some cases I would like to see also to see private methods
(especially when trying to understand the internals of a collegues code
or even to browse throught the internals of my own code)

Therefore I wonder whether pydoc could be configured such, that it would
also display private methods (the ones with leading underscores)

If not:

What tools / methodologies would you recommend to quickly browse own /
collegues source code.

In many cases the function prototypes and the doc strings of public and
private methods would be sufficient for me.

thanks for any ideas

Python 2.6 and up behaves exactly as you want.
On previous versions you may use this:

class MyXMLRPCServer(SimpleXMLRPCServer.SimpleXMLRPCServer):

... your methods ...

if not hasattr(SimpleXMLRPCServer.SimpleXMLRPCServer, 'shutdown'):

# pre 2.6
quit = False

def serve_forever(self):
while not self.quit:
self.handle_request()

def shutdown(self):
self.quit = True

def server_bind(self):
self.socket.settimeout(1.0)
SimpleXMLRPCServer.SimpleXMLRPCServer.server_bind(self)

It appears this is easier than I thought. MLB's plot will do it. I can
put arrows at the end of a line, and even use sleep to watch the path

It's definitely *not* exactly a programming challenge, but algorithm
challenge.

A programming (only) challenge should only require the players to write
codes to implement an algorithm.

This one requires both algorithm design & programming.

Use Linux. (On Linux, Glut returns mouse wheel events as buttons 4 and
5), or use FreeGlut. On both Windows and Linux freeglut returns mouse
wheel events as buttons 4 and 5.

From: darnzen

I've written an app using the wck library (widget construction kit,
see http://www.effbot.org), in addition to the wckGraph module. What
I'd like to do, is take the output of one of my windows (happens to be
a graph), and save it as a *.png or *.gif. I was planning on using the
PIL for this. I'd like to use the code I have as is, without re-
writing all the graphic calls to use PIL methods.

WCK uses its own "pixmap" class for storing images in memory. I can't
find any documentation or class reference for pixmap and what I find
in the source is confusing.

Does anyone have any direct experience with these libraries that can
tell me that there's some super easy thing I'm missing? I'd love it if
the wck pixmap is compatible with PIL. I don't have the time to mess
with it unless I know its going to work.

Try moving the redirection out of the command:

You can't use dots neither in module names nor package names as they're
identifiers [1]. It's like trying to use an attribute named 'foo.bar': you
can handle it with getattr/setattr, but normal attribute access won't work:

py> x.foo.bar = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: X instance has no attribute 'foo'
py> setattr(x, 'foo.bar', 1)
py> x.foo.bar
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: X instance has no attribute 'foo'
py> getattr(x, 'foo.bar')
1

The only sane solution is to avoid using dots in package names. Sorry, but
having project.api.config, project.api.contacts as directory names is
simply crazy.
Looks like you actually wanted to use this layout:

project/
api/
config/
...
contacts/
...
core/
...

but made a wrong turn in the road...

Note the *literal* part. If you (the programmer) is likely to know the
parameter value when writing the code, then the function is actually two
separate functions.
By example, foo.get_path(absolute=True) should be written as
foo.get_absolute_path() and foo.get_relative_path()
It gets worse when one parameter alters the type of the returned value, or
even the number of returned values. This is an actual example:

def build_image(self, zone=-1, return_sizes=False):
...
if return_size:
return img, sizes
else:
return img

image = foo.build_image(3)
but:
image, sizes = foo.build_image(3, True)

It should be split onto two separate functions; in this particular case,
computing 'sizes' required actually drawing the image, so the solution was
to make those 'sizes' attributes of the returned image.

I'd suggest a couple more tests.
Open the Python interpreter and execute:

py> from idlelib import idle

This *should* launch IDLE, or raise an error... If nothing happens, exit
the process and open another one, and execute:

py> import Tkinter
py> root = Tkinter.Tk()
py> root.mainloop()

An empty window should appear. If not, I'd say something is wrong with the

PIL has an impressive compatibility record - it works with *any* Python
version from 1.5.2 up. You should be able to use PIL with 2.4 without
problems.

CAR INSURANCE FRAUDS ARE VERY HIGHGLY GOING ON IN AMERICA:

LOS ANGELES:
Due to bad economic conditions in america the people
cheated the insurance company.They hiding their cars in some place and
they claim insurance from insurance providers telling that their car
was damaged or theft.This was the situation going on in america. The
people in middle class were effected due to the bad economical
reasons.

I don't see what you gain by doing that.

On the other hand, you might check whether the queue contains exactly one
item and it is None, just to be sure that all queued work has been done.

(BTW, I'd use a different sentinel instead of None; perhaps this could not
happen in your current code, but it's easy to inadvertedly put a None in
the queue, stopping all workers prematurely.)

That was my point. I didn't think I needed to care, but I wanted to be sure
I was not missing something.

I will just discard all the final cleanup code.

Good advice.

Thanks, Gabriel

Would this work without an internet connection? The original poster
stated that internet isn't so reliable, hence the need for a local solution.

I just wanted to give my opinion on Dell Inspiron 15 and let you know
that I was extremely pleased to get my new lap top!!!! What a pleasure
it has been!!!! It took a little while to get because I ended up
getting a design on my laptop. I like the pretty designs better than a
plain black top. I love love love my new laptop!!!! It was a New Year
present to my self this year and I couldn't be happier!!! It is
extremely fast!

The only thing I do not like about it is that the keyboard does not
have the numbers on the side, they only run along the top. I enter in
a lot of numbers in one day and it just takes a few extra minutes
doing it with them on the top. Also I forgot to have them install the
home and office thing on here so I have to run out and buy that but
everything else is just perfect.
