gast: Generic Python AST

gast provides a compatibility layer between the Abstract Syntax Trees (AST) of various Python versions (including Python 2 and Python 3), offering a homogeneous API compatible with the standard library `ast` module. It abstracts away version-specific differences in the AST structure, making it easier to write tools that work across multiple Python versions. The library is currently at version 0.7.0 and remains actively maintained.
