Is there a scope analyzer for Python?

Question

Given a python file, I want to find out all of the scopes and declarations for the identifiers in the file.

For example, given this file:

import a
from b import xyz

def my_func(g):
   print "2"

my_func(0)
a.function_in_a(3)
xyz(4)

I want the output to be:

• on line 7, my_func refers to my_func defined in line 4 of this file
• on line 8, a refers to the module a. function_in_a refers to the function defined in module a
• on line 9, xyz refers to the function defined in module b

Is there a library that does this for me? Basically I'm trying to use the in the context of IDE functionality / code autocomplete / understanding scopes of variables. Basically, I'm interested in understanding the location of an identifier's (variable, function, etc) definition, much like how an IDE like PyCharm determines it.

Strange that I haven't seen this issue before.

There's jedi.names, which would do pretty much what you want!
