Just a general question

Hello,

I just had a basic question.what are bindings for?How do they help in execution of python scripts?What language are they written in?What are wrapper classes?

Bindings make the C++ objects accessible from Python. This
documentation describes them and the process to generate them:

The API definitions for ns-3's libraries are written in Python, and a
tool called 'pybindgen' generates the C++ binding code which is then
compiled and linked to form the Python module. So, technically, the
bindings are in C++ but that C++ code is generated by the bindings
generator pybindgen.

You may want to review pybindgen's tutorial for answers to these types
of questions:
