[Tutor] FW: Comparing variables

[Karthik Gurumurthy]

is it something like you have 
numStr = "1"
then you can get integer 1 by doing 
int(numStr)
but it might throw an exception depending upon what came from web page
so you might want to catch it though

try:
 num = int(numStr)
except: ValueError
 //do something here

karthik.
