Introduction to ASTutor

ASTutor is a specialized interactive platform designed to educate users about Python's Abstract Syntax Tree (AST) module. It provides an in-depth exploration of how Python's AST works, guiding users from the basics of AST generation and manipulation to advanced topics such as custom node visitor creation, node transformers, and AST analysis for static code analysis. ASTutor aims to demystify the complexities behind Python's syntax and execution by breaking down code into its fundamental building blocks, making it an invaluable resource for learning and mastering Python's AST. For example, users can learn how to parse Python code into an AST, inspect the structure of the AST, and even modify or generate new code programmatically. Scenarios illustrating these aspects include debugging code by analyzing its AST for common patterns that lead to errors, or creating tools that automatically refactor code by modifying its AST.
