As for other resources, I recently came across this:
http://farmdev.com/talks/unicode/
This was the first explanation that really made me understand the
difference between Unicode and utf-8 (and realize that I'd been using
the terms 'encode' and 'decode' backwards!). Anyway, just one more

How about:
def length(self):
return math.hypot( *(self.p1 - self.p2) )
Compiled C code will be much faster than squaring and square rooting.

Here's an example from django which I am using, but I asked on this list
since it seems more related to python than the web framework:
class Contact(models.Model):
first_name = models.CharField(max_length=30, blank=True)
last_name = mod

I'm trying to translate the following VB code into Python and not
sure how to
create an array of variants.
An array of variants in Python is a list.
But I'm not sure why you think you need one?
VB Code:

Hmm. I don't understand the LSP to make any requirements on the
constructors. It says that instances of a subclass should be

Constructors as a separate language entity is an idea born of C++,

Hi, folks.

I could create a list of all the variables and then iterate over them,
dropping the ones which are empty, then join() and return them; however, I
am guessing there is another way to get that

John,
Thanks for your reply. I'm aware of list, tuple, sets, etc. and have tried them,
which results in an error: Invalid argument type in SetXData method. My
understanding is that I do need an array here. Just don't know the correct way
of doing it.
