Hi Jim,
If your new to Python and coming from Perl then your question above
needs knowledge of Python Exceptions, and the try statement.
if you had variables x and y and wanted to compute x/y but if y was
zero print some message and continue, then you would most likely do
something like:
x = 1
y = 0
try:
z = x / y
except ZeroDivisionError:
print "This leads to a divide by zero error!"
There is more info in the tutorial chapter 8.
