this module annotates Python abstact syntax trees (ASTs) with the positions of tokens and text in the source code that generated them It makes it possible for tools that work with logical AST nodes to find the particular text that resulted in those nodes, for example for automated refactoring or highlighting. It works with Python3 and can annotate both trees built by ast, and those built by astroid. This (source) is downloaded from pypi.org/projects/asttokens as the github site may not have a complete sourcecode zip.
