Making a Python interpreter in 1024 bytes

Austin Henley shares his challenge of building a Python-like interpreter in just 1024 bytes of C code, with no macros or external libraries.

Background

Code golf and interpreter challenges are popular among systems programmers. Austin Henley is known for creating minimal implementations of programming languages and tools.
