[rox-devel] Silly Python Question

[Christopher S. <che...@ya...>]

I've got another silly python question:

How can I check to see if a variable exists?  I thought I could do something like:

if var['field']:
     do some stuff

But that fails at runtime, telling me that var['field'] is not defined!  In PHP, there are empty()
and isset() functions that will allow me to test for variable existance.   Is there anything like
that in Python?  I looked in the library reference, but didn't see anything.

Thanks,

Chris
