astatine
Some handy helper functions for Python's AST module.
Decision gist · record as of 2026-08-14
Yes, if you're writing tools that parse or manipulate Python code and need to support multiple Python versions. The low install friction, permissive license, active maintenance, and zero known vulnerabilities make it a safe choice. Not worth installing if you only target a single Python version or don't work with the ast module.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6 or later; the package is designed to smooth over AST differences across supported Python versions.
- Low friction: pure Python wheel with only two runtime dependencies (asttokens and domdf-python-tools).
- Actively maintained as of 2026-04-07, though last release was 2023-08-15.

What it is and what it does
Astatine is a utility library that wraps Python's built-in ast module with helper functions to work around version inconsistencies. The ast module itself has changed between Python releases, making it difficult to write code that works reliably across versions; astatine abstracts those differences away. It depends on asttokens and domdf-python-tools to provide its functionality.
The package is in Beta status and actively maintained. It supports Python 3.6 through 3.11 on both CPython and PyPy, and is distributed as a pure Python wheel with no compiled dependencies. It's typed (includes type hints) and has no known security vulnerabilities.
Use it for
- Normalize AST handling across different Python versions in a code analysis or transformation tool
- Build linters or code quality checkers that need consistent AST access across Python 3.6–3.11
- Simplify AST-based code generation or refactoring scripts by using stable helper functions
- Develop Python parsing libraries that need to support multiple Python versions without version-specific branching
