I'm new to Python and can't readily find the appropriate function for
the following situation:
I'm reading in a byte stream from a serial port (which I've got
working OK with pyserial) and which contains numeric data in a packed
binary format. Much of the data content occurs as integers encoded as

Yes, I just tripped over that, in fact, hence the error in my original
post. I supp
A Python newbie, but some basic understanding of how classes, objects
etc work in eg VB.Net. However, I'm struggling a little to translate
this knowledge into the Python context.
I'm trying to teach myself this aspect of Python by working up a trial
project, part of which calls for pulling in data
Many thanks for the speedy replies.

May I ask a simple newbie question, which I presume is true, but for
which I can't readily find confirmation:
Let's say I have a parent class with an __init__ method explicitly
defined:
class ParentClass(object):
def __init__(self, keyword1, keyword2):
etc
and I subclass
Thanks for the responses - they're much appreciated. And I understand
the slight impatience with questions that could possibly be answered
without recourse to a forum - I'm usually in the opposite position of
fielding many newbie questions in a forum in a completely different
field!
But don't be t
I'm learning Python using the Komodo Edit freeware code editor. One
thing I'm finding a little confusing is that the code completion lists
(what I would call Intellisense coming from a .Net background) are
often very incomplete, especially with imported classes like wx. It's
like KE can't look far
Trying to learn Python here, but getting tangled up with variable
scope across functions, modules etc and associated problems. Can
anyone advise please?
Learning project is a GUI-based (wxPython) Python program that needs
to access external data across a serial port.
The first thing that I need
Many thanks for the repsonse - much appreciated.
And sorry - yes I was probably compounding two separate issues here -
the GUI one and the variable scope one. Maybe the wxPython list would
be the best place to ask more about the GUI side of things.
Then actually I can simplify my remaining quest
I need what I'd call (in .Net) a timer, ie I need to run a function eg
every 2 seconds - it doesn't need to be millisec accurate but it would
be nice if it wasn't eg every 4 seconds or something.
Rather surprisingly, Core Python (Chun) doesn't seem to index 'timer'
or 'scheduler', which leaves me
