So, here's another simple example where all of the radio buttons
start out incorrectly selected:
v = StringVar()
Radiobutton(root, text = "Test RadioButton 1", variable=v,
value="1").grid(row = 0, column = 0, sticky = W)
Radiobutton(root, text = "Test RadioButton 2
Thanks for the reply. Unfortunately, even when I include a
variable, all of the buttons start out selected. I noticed that this is the
case when I create a StringVar (rather than an IntVar, where the buttons start
out correctly unselected). So, here's another simple example wh

Data validation is also a good thing:
I agree with this bit but...
def mysum(n1, n2):
try:
n1 = int(n1)
n2 = int(n2)
except ValueError:
print "Error! Cannot convert values to int!"
return n1+n2
Or do something similar.
In a dynamic language

Thanks for the tip on enumerate, escaped me. Much like Kent's simply
using a temporary var escaped me despite having done similar things

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

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
