I am using Sphinx to document my Python project. This shows me all the methods of the project, but not any variable. I want to be able to list all variables too.

My code.rst is -

```
Code Documentation
=====================
.. automodule:: sql_fn
   :members:

```

Currently, my python project goes like this-

```
#test variable
var=0
test_fn():
    '''test function'''
    print "hello world"

```

How do I change code.rst or my project to show my `var` and it's description `test variable` also?
