Just note that both solutions rebind the name to a newly constructed
list instead of modifying the original list in place. This is usually

Coming from C++, you'll probably need a few days to grasp Python's
object model and idioms (Python looks much less like a dumbed-down C++

Test2(2,True) calls Test2.__init__() with a Test2 instance 'self' and

OMG. optparse is far better than this.

My overall feeling is that in most function, you're mixing too much
different concerns. Each function should do *one* thing (and do it
well). The most obvious problem here is about mixing application logic
and UI. Application logic (what your app is effectively doing) should be
as independant as possible of UI concerns. If possible, you should be
able to reuse most of the application logic (except for the main() func,
which in your case is the command-line UI) as a module in other
applications. Now there are time when the application code needs to
notify the UI. The good news is that Python makes it easy to makes this
generic, using callback functions or objects provided by the UI and
called when appropriate by the application logic. The key here is to
come up with a clear, well-defined interface between logic code and UI code.
A last point : avoid globals whenever possible. Either pass values as
arguments to functions or use a kind of config object if there are too
much configuration stuff.

Remember the 3 golden rules about optimisation:

Heck, compared to PC-Soft, one could find that Microsoft's marketing

f = StringIO.StringIO(long_string)
chunk = f.read(chunksize)
while chunk:
yield chunk
chunk = f.read(chunksize)
f.close()
Now I'm sure someone will come up with a solution that's both far better
and much more obvious (at least if you're Dutch )

ery nice which is the interactive python
shell. This lets you try code snippets and see by yourself how it really
works :

property is not function, it's a class. And it doesn't "overwrite" anything.

Certainly not the way Pyt
body (ie, outside methods) are attached
to the class object itself (and then shared by all instances of the
class), not to instances themselves. Instance attributes initialisation
is usually done in the __init__(self, ...) method.
