I have found an interesting topic and am going to work on a project  "Nested  Classes". It parses the code of nested classes written in  C++  to other object oriented languages.It has already done to convert C++ nested classes code into C# and Java code.I am going to code which converts C++ nested classes code in python code.It will be really helpful if anyone will suggest how shoud i begin with it.
Thank You,
