You can use the observer pattern.


class Observed(object):
def register_observer(self,observer):
self.observer=observer
def notify(self):
self.observer.update(self)
...

Let me give you an example.
There are two files. The first is compute.py and has the code:

def sumup(a,b):
return a+b


And there is your program, main.py

import compute

First of all, please read this (http://www.daniweb.com/forums/announcement114-3.html). It is on the very beginning of the forum. Your indent cannot be reconstructed from your post, so your code can...

Your code is not intended in the function.

try:

def getText(inFile):
text=[ ]
file = open( inFile, "r" )

for line in wholefile:
line = line.strip()

Try open the server port higher (>5000).

Check out if minimal (http://www.prasannatech.net/2008/07/socket-programming-tutorial.html) implementations are working.

If you simply drop the else part, then you will have all lines in the text, which do not begin with "<" and do not end with ":>"

for line in wholefile:
line = line.strip()

Maybe reading a tutorial is helpful. I have never written a pygame game, all my answers come from googling pygame tutorial and getting the code from there.

In your other thread (http://www.daniweb.com/forums/thread193501.html) the image shows up. I've checked.

You should check the type first, and if it is a keyboard event, than get the key pressed.

while True:
clock.tick(60)

This is not true, or you did not show us that. Your code does not produce the desired output, and it is not, that it has numbers instead of characters.

I think the problem:

Yes. The clear function can be just print("\n"*55).

Second, the magic instance should execute functions in device instance.

I cannot find anything usable in metaclass for that. I am not smart enough maybe.

Why should the Device inherit? The class in device can have an object reference to an attribute object and can...

I think this is the case where metaclass is usable.
I've never thought that it is usable for anything at all:)
I am happy that I see a real use case for it.

I look up the metaclass...

I am interested.
Can you give me a stripped down example? If you have time for that.

I have read the problem description several times, but could not understand it.

Maybe your solution is...

Yes, please, try to elaborate on the problem.
Dynamic module loading can mean different things, but I think you need that.

For example wxpython uses the semantics:

Besides, that you do not have a "primary" module in the code...

What you really want imho is to inject code.

But if you want it to be verbose, than the following questions need to be answered imho:

Is this a real ID? One ID <-> One name?
You have to have an algo to make an ID from a name and make a name...

If the ID-s don't have to be verbose, then you might consider the uuid module.

The title of the forum is about duck typing. The problem at hand has nothing to do with it IMHO.

I agree. Re.findall function is not so well suited for taking a user input regular expression,...

What is the problem with filtering?

I suppose you have a function, that tells if a list member contains cake. Does this function behave unexpectedly?

I think this function should look like:...
