AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Annotates Python abstract syntax trees with the precise source code positions and text of tokens, enabling tools to map logical AST nodes back to their originating code for refactoring, analysis, and transformation.

Installs with no runtime dependencies and low friction; actively maintained with a recent release 32 days ago and active repository status.

import asttokens, ast
source = "Robot('blue').walk(steps=10*n)"
atok = asttokens.ASTTokens(source, parse=True)
attr_node = next(n for n in ast.walk(atok.tree) if isinstance(n, ast.Attribute))
print(atok.get_text(attr_node))

Verdict: A stable, actively maintained library with zero known vulnerabilities, no external dependencies, and broad Python version support (3.8–3.14). Well-suited for code analysis and refactoring tools that need to bridge AST nodes and source text.

Needs verification

• Whether the package works equally well with both ast and astroid-built trees in practice, or if one has limitations.
• Performance characteristics when processing very large source files or deeply nested AST structures.
