How to call methods defined in python in a node written in C++

edit

Hi,

I want to call quat_to_angle() and normalize_angle() methods defined in calibrate.py in the turtlebot_calibration package in my node written in C++. There is no header file generated of calibrate.py, so is there any way that i can use these methods in my C++ code without rewriting these methods in C++? If not then can u please tell some alternate implementations of these methods already done by someone else?

Thanks

Regards

Usama
