Developer creates Python interpreter in 1,024 bytes of C code using recursive descent parser, limited syntax subset, no error handling to mimic Python's distinctive features like colons, indentation and def statements.

Making a Python interpreter in 1024 bytes

Austin Z. Henley I build tools for people 9/6/2026 To feel human, I write code by hand on the weekends. My latest challenge? Make a Python interpreter in 512 1024 bytes of good ole C code. Oh, and no macro shenanigans or library tomfoolery. def buzz(): for n in range(101): if n % 15 == 0: print("FizzBuzz") else: if n % 3 == 0: print("Fizz") else: if n % 5 == 0: print("Buzz") else: print(n) buzz() I probably can't fit all of the Python language into an interpreter that is only 1024 bytes of code....
