I'm using the SimPy package to run simulations. Anyone who's used this

want to combine these sequences into common functions. The problem of

generator and its behavior changes.

I actually found a reasonable answer to this, I think. If one of the
called functions contains a yield, that function is by definition a
generator,
A nomenclature note: a function with yield is a 'generator function'. It
is an instance of the 'function' class, same as for any other def
statement (or lambda expression). It returns an instance of class
'generator, as you note here

It is the result, and not the function, that is the generator (a type of
iterator).
