Dive into CPython's internals by implementing a new pipe operator in this PyCon US talk. Explore the CPython source code, learning about Python's grammar, syntax trees, and core language features. Follow along as the speaker obtains the source code, regenerates parser and token files, and compiles a modified version of CPython. Gain insights into writing and running tests for implementation changes. Suitable for those interested in exploring CPython internals, with some Python knowledge helpful but not required. Basic C programming is used, but prior experience is unnecessary. Acquire a mental framework to aid in understanding more comprehensive resources like the Python Developer's Guide.
