If you truly wanted to recreate this type-bondage style of programming 
in Python, it's easy enough to do.
Where you would write in C++:
// Type matching will get checked at compile-time
void my_function(MassivelyParallelFrobinator& mpf, OtherThing& ot) {
 blah, blah, blah
}
you could write in Python:
# Type matching will get checked at run-time
def my_function(mpf, ot):
 assert isinstance(mpf, MassivelyParallelFrobinator)
 assert isinstance(ot, OtherThing)
but that's just not the way people write code in Python.
