Did you try to use pygments?

http://pygments.org/docs/api/

It already contains a lexer for Python source code. You can create a 
Lexer (pygments.lexer.Lexer) then call its get_tokens method.

Then you can use this to identify statements:

http://docs.python.org/reference/simple_stmts.html

Fortunately, almost all statements begin with a keyword. There are some 
exceptions:

     expression statement
     assignment statement

I would first tokenize the code, then divide it by statement keywords. 
Finally, you just need to find expression/assignment statements in the 
remaining sections. (Maybe there is a better way to do it.)
