You'd want to do it with paired keywords, in the manner of try/except,
to avoid utterly breaking Python's syntax conventions.  Perhaps
something like this:

do:
   p = a / b
where:
   a = 20 / len(c)
   b = foo(d)

or even:

where:
   a = 20 / len(c)
   b = foo(d)
do:
   p = a / b


Effectively you're creating a little local namespace for temporary
variables.  I'm not sure it buys you a lot, even as sugar, and I'm
really not convinced by the bypartite form, but it's definitely
possible.
