  ...instead, we recommend that you use something like IDLE (which stands for Integrated DeveLopment Environment), which is included in the installation Python files on any platform that supports Tcl, including Windows. As for yourself, if you prefer programming directly from a terminal window, a better choice than the default interpreter might be IPython. In addition to IDLE, there are a number of third party tools which you can find out by referring to the Python Editors Wiki and the Python Integra...

Cog reads and writes the same file, and can be run over and over again without losing information. Cog processes text files, converting specially marked sections of the file into new content without disturbing the rest of the file or the sections that it executes to produce the generated content.

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.

  ...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...
