The PSF is also financially supporting CPython through a complete migration to GitHub and, in 2019, allocated $19,000 USD to assist CPython with Python 2 sunset communications. The PSF hosts the annual Python Language Summit at PyCon US. The Summit is a small gathering of Python language implementers (both core developers of CPython and alternative Pythons), third-pa...

  ...ing language within a larger software system. In this case, Python code can invoke specific functions of that system, even if those functions are written in C or C++. And C and C++ code can easily make calls back into Python code as well. Using this capability, ILM integrated Python into custom applications written in C or C++, such as ILM's in-house lighting tool, which is used to place light sources into a 3D scene and to facilitate the writing, generation, and previewing of shaders and mater...

It returns an instance of the class Instance, which is defined next. The class Instance is the class used for all instances of classes built using the Tracing metaclass, e.g. aninstance. It has two methods: The __init__ method is invoked from the Tracing.__call__ method above to initialize a new instance. It sav...

They use Python both for end user programming and in the implementation of large parts of their system (almost everything except the rendering engine). They probably have the most extensive and best-documented case study of teaching Python programming (albeit in a limited domain) to users with no prior programming experience, and their enthusiasm for Python has been a great encouragement for us to consider using Python in a general programming c...
