AST Unparser for Python

astunparse is a Python library that provides an Abstract Syntax Tree (AST) unparser, allowing conversion of ASTs back into Python source code. It is a standalone, factored-out version of the `unparse` utility originally found within the Python source distribution itself. In addition to unparsing, it offers a `dump` function for pretty-printing AST structures. The current version is 1.6.3, released in December 2019, and it has a low-frequency release cadence, primarily updating for compatibility with newer Python AST changes.
