CPython Internals: Your Guide to the Python 3 Interpreter

Are there certain parts of Python that just seem like magic? Like how dictionaries are so much faster than looping over a list to find an item. How does a generator remember the state of the variables each time it yields a value and why do you never have to allocate memory like other languages? It turns out, CPython, the most popular Python runtime is written in human-readable C and Python code.

This book will explain the concepts, ideas and technicalities of CPython.

We’ll cover all the concepts behind the internals of CPython, how they work with visual explanations as you go.

You’ll learn how to:

  • Read and navigate the source code
  • Compile CPython from source code
  • Navigate and comprehend the inner workings of concepts like lists, dictionaries, and generators
  • Run the test suite
  • Modify or upgrade components of the CPython library to contribute them to future versions

Take your time for each chapter and make sure you try out the demos and the interactive components. You’ll soon feel a sense of achievement that you grasp the core concepts of Python that can make you a better Python programmer.
