interpreted

A Python interpreter, written from scratch in Python.

This interpreter is made solely as the base for my talk, "Writing a Python interpreter from scratch, in half an hour.", but is now being used as a project to learn how interpreters work.

Feel free to open up issues, pick up tasks, and ask questions.

Installation

pip install interpreted

Usage

$ cat foo.py
print("2 + 2 is", 2 + 2)

def greet(name='User'):
    print('Hello,', name + '!')

greet()

$ interpreted foo.py
2 + 2 is 4
Hello, User!
