(cod[p],p+1) is a two-item tuple with [0] equal
There's a little forth program written in python here
#http://openbookproject.net/py4fun/forth/forth.py
I'm struggling to understand what these lines mean.
def rJnz (cod,p) : return (cod[p],p+1)[ds.pop()]
def rJz (cod,p) : return (p+1,cod[p])[ds.pop()==0]
Specifically I'm stuck on what (code[p],

Wow, this is incredibly useful! I can understand why an introductory
book wouldn't make use of them, but I am really glad to know about

I'm sorry for such a basic question, but I haven't been able to phrase
a search that gets me an answer and my books are totally silent on
this. I have seen a number of python function defs that take
parameters of the form (**param1). Looks like a pointer... but my
