In this detailed Python tutorial, you’ll explore the CPython source code. By following this step-by-step walkthrough, you’ll take a deep dive into how the CPython compiler works and how your Python code gets executed.

Are there certain parts of Python that just seem magic? Like how are dictionaries 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 tutorial will walk you through the CPython source code.

You’ll cover all the concepts behind the internals of CPython, how they work and 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
