🖥 Python interpreter written in Python in 500 lines of code

Byterun is a Python interpreter. While working on Byterun, the author discovered that the fundamental structure of the Python interpreter easily fits within the 500-line size limit. This article examines the structure of the interpreter and provides context for further study.

 The goal is not to explain everything there is to know about interpreters - as in many other interesting areas of programming and computer science - you can spend years developing a deep understanding of this topic.

Byterun was written by Ned Batchelder, drawing on the work of Paul Schwartz. Its structure is similar to Python's main implementation, CPython, so understanding Byterun will help you understand interpreters in general and the CPython interpreter in particular.
