  • What is Py++? Definition: Py++ is an object-oriented framework for creating a code generator for Boost.Python library. Py++ uses few different programming paradigms to help you to expose C++ declarations to Python. This code generator will not stand on your way. It will guide you through the whole process. It will raise warnings in the case you are doing something wrong with a link to the explanation. And the most important it will save your time - you will not have to update code generator script every time source code is changed.

  • To control the creation and initialization of the class in the metaclass, you can implement the metaclass’s __new__ method and/or __init__ constructor [6]. Most real-life metaclasses will probably override just one of them. __new__ should be implemented when you want to control the creation of a new object (class in our case), and __init__ should be implemented when you want to control the initialization of the new object after it has been created.

  • It’s important to note here that these print-outs are actually done at class creation time, i.e. when the module containing the class is being imported for the first time. Keep this detail in mind for later.
  • So when the call to MyMeta is done above, what happens under the hood is this:
