Hi,
This is a little off-topic, but, I though I might put this question in.
Since I am learning Python, I was wondering if there are any good
references on secure
coding practices. Books, guides or even any howtos would suffice.
Security seems to be almost always an after-thought rather than bei

Am I right in this thinking... or does it not save me any more bytes in

The reason I thought that closing the file after I've written about 500MB

Oh yea, it's python 2.6.

Data validation is also a good thing:
I agree with this bit but...

print "Error! Cannot convert values to int!"
return n1+n2
