My local copy of OCaml MiniPy

A Naive (OCaml) interpreter for a (minimalist subset of a) Python like language.

Try the interpreter online or use the editor (these rely on js_of_ocaml).

This is a work in progress, most of the supported features are only partially implemented.

Screenshots

Here is an example of using the MiniPy OCaml console, to define a sum function. It shows that a lot of basic construct of the Python language are supported, but almost no functions from the standard library are available:

Here is a second example, using the MiniPy OCaml editor, loaded with one of the example files, showing a Eratosthene Sieve to detect prime numbers:

Here is a third and last example, using the MiniPy OCaml editor, loaded with one of the example files, showing the prime decompositions of integers. I added a few comments (# blabla) to show some features supported by MiniPy:
