What it is and what it does
ast_decompiler takes a Python AST object and generates human-readable Python source code from it. This is useful when you have parsed code as an AST (via ast.parse or similar) and need to recover or inspect the original source, or when you're working with dynamically constructed ASTs and want to see what code they represent.
The package supports Python 3.8 through 3.13 and has no runtime dependencies, making it lightweight to integrate. It is actively maintained with recent activity, and the codebase is formatted with Black. The module is straightforward to use: pass an AST node to the decompile function and receive a string of reconstructed Python code.
Use it for
- Debug or inspect dynamically generated or modified ASTs by converting them back to readable code.
- Implement code transformation tools that need to display or log the result of AST modifications.
- Build educational tools or documentation that show how Python code maps to its AST representation.
- Generate test fixtures or example code from programmatically constructed AST objects.
