Given that Frank originally stated this

"
I have a requirement where I need to sequentially execute a bunch of 
executions, each execution has a return code. the followed executions 
should only be executed if the return code is 0. is there a cleaner or 
more pythonic way to do this other than the following ?

if a() == 0:
     if b() == 0:
         c()
"

I can only see one way that you can possibly intepret it.  Perhaps rr 
was dashing off a reply on a mobile device while doing a home run, hence 
wasn't concentrating on what Frank had actually said?
