Source code and examples for the 'Let's Build A Simple Interpreter' blog series, which teaches how to build a basic interpreter in Python step by step. It covers lexing, parsing, abstract syntax trees, semantic analysis, scopes, and procedure calls across 19 parts.
Use cases
- learn how to build an interpreter from scratch
- understand lexers and parsers hands-on
- study abstract syntax trees with runnable code
- learn how call stacks and activation records work
- teach compiler fundamentals with a guided series
When to choose
- you want a tutorial-style, incremental introduction to interpreters
- you prefer learning by running and extending working Python code
- you need a gentle on-ramp to compilers and language implementation
When to avoid
- you need a production-ready interpreter or language runtime
- you want a comprehensive compiler textbook or formal theory course
- you need a modern language toolchain rather than educational code
