I may be having a brain fart, but is it at all possible to have a
function first return a value then continue its calculation. Like this
simple example:
my_var = 5
def my_function():
return my_var
my_var +=1
This obviously won't work as written but is there a cleaver way around this.

I'm interested in studying the itertools source code, especially the
permutations function.
However, I cannot find the library. Where could I find it?
