Making a Python interpreter in 1024 bytes

A Python interpreter was created in just 1024 bytes of C code, without using any macro tricks or libraries. The author, inspired by the challenge, managed to craft a program that exhibits Python-like behavior despite its extreme size constraints. This interpreter reads Python source code, tokenizes it, parses it into an abstract syntax tree, and then executes the code directly.

It lacks error handling and makes several assumptions about the input, such as correct keywords and token boundaries. The interpreter is limited to single, lowercase variable names and performs function calls by jumping back to execute the function body, then restores the previous state. Despite its small size, the interpreter supports features like arithmetic operations, if statements, loops, and function definitions, all while keeping memory usage minimal.

The author shares their code on GitHub for others to explore, demonstrating the ingenuity required to achieve such a complex program in such a small space.
