GoKawiilDeveloper builds a working Python interpreter in just 1024 bytes of C
Austin Z. Henley, a Microsoft engineer, built a minimalist Python interpreter written in C that fits within 1024 bytes of code, after an initial attempt at 512 bytes proved too small. The interpreter supports a limited subset of Python syntax—including def, colons, indentation, and parenthesis-free if statements—enough to run a FizzBuzz program, but skips CPython's full tokenizing, AST, and bytecode pipeline in favor of global variables and a fixed-length array.
