astroid 4.2.0b5

An abstract syntax tree for Python with inference support.

Professional support for astroid is available as part of the Tidelift Subscription. Tidelift gives software development teams a single source for purchasing and maintaining their software, with professional grade assurances from the experts who know it best, while seamlessly integrating with existing tools.

What’s this?

The aim of this module is to provide a common base representation of python source code. It is currently the library 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.
