Python Lox Interpreter

Description

An (incredibly bare bones) Python 3.9.2 interpreter implementation of the lox programming language, adapted from the jlox tree-walk interpeter in the book "Crafting Interpreters" by Robert Nystrom.

I put "bare bones" because currently the interpreter only supports a few of lox's basic features so far:

• Literals (strings, floats)
• Basic Arithmetic (+, -, *, /)
• Boolean Arithmetic & Equality
• Expressions
• Statements (only print & var)
• Variable Declaration
• Variable Assignment
• Comments (single & multi-line)
• Block Statements & Scope
• If/Else Statements
• While Loops
  I plan on adding more as I progress through the book

Huge thank you to Bob Nystrom for letting me dive into the monstrosity that is compiler/interpreter programming with Crafting Interpreters
