1) What exactly is a Nodehandle? Why are they only in C++ and not in Python? 2) In many C++ header files of a ROS package (for example this one), I have seen people declaring 2 NodeHandles namely, nh_ and nh_priv_. Why are there 2 NodeHandles in the same code and what does the underscore _ at the end of both the identifiers mean? Would like to know about these in more detail, resources would be amazing to get. Help is appreciated, TIA
