thanks all you guys. I have find the solution which is quite simple by using 
sys._frame(1).f_locals in function to get the caller's scope
The following is my user case:
I am writing a tool to translate python code to cython code then compiled using 

jit, build=make("mymodule")
#jit function collect python code and signature then translate to cython code
    int b;
def f(a):
    return a+1

build()# compile cython code and load compiled module then expose compiled 
function to current namespace. So this is my purpose to get caller's scope
f()# now f is a compiled function
