Does PyModule_GetDict return information about class method variables?

It does not exist in the module or the function object but on the stack. 
Let's go to C again:


void baz(void);

void foo(void)
{
    int bar = 42;
    baz();
}

How do you get from `baz()` the value of `foo()`\s local `bar`?  Other
than ugly non portable stack trickery!?

Why don't you just give the object as argument to your C function? 
Wanting to poke around in the callers name space is code smell.  Don't do
that.
