astroid 2.0

A abstract syntax tree for Python with inference support.

What’s this?

The aim of this module is to provide a common base representation of python source code. It is currently the powering pylint’s capabilities.

It provides a compatible representation which comes from the _ast module. It rebuilds the tree generated by the builtin _ast module by recursively walking down the AST and building an extended ast. The new node classes have additional methods and attributes for different usages. They include some support for static inference and local name scopes. Furthermore, astroid can also build partial trees by inspecting living objects.
