Note: Ensure that you remove the embedding when going to production, as it’ll interrupt your Python script. Of course, you can leave it if you want to use the interactive shell as a part of your program. Ensure that you’ve defined all the code that you’d like to play around with...
However, when Python encounters an error while running a script, the execution stops. In other words, the program crashes. In chapter 8 of Python Basics, you’ll learn how to handle errors so that your programs don’t crash unexpectedly.Things...

To do this, you would simply run the Pydoc as a script but with a -b argument which will start an HTTP server on an arbitrary unused port and open a Web browser to interactively browse the documentation. This is helpful, especially when you have various other services running on your sys...
Any script executed through the vsscript api (that means vspipe, avfs, vsvfw or other API users) will have __name__ set to “__vapoursynth__” unlike normal Python scripts where it usually is “__main__”.VapourSynth Structure Most operations in the VapourSynth library are performed ...
