Question: How to walk/visit the AST?

I'm trying to extract all the imports from a python file. To do this I'm using the rustpython_parser::parse function to get an AST and then iterating over all the statements in the body to find Stmt::Import and Stmt::ImportFrom. This works for imports defined at the root of the file, however misses any imports defined inside e.g. function/class definitions etc. So I think what I really want to do is walk the AST and visit all the nodes. Is there some way to achieve this with one of the rustpython packages?

rustpython_parser::parse エントリポイントと body 内の AST 文から始めます。RustPython パッケージに既存の AST visitor または traversal API があるか確認し、それで関数定義やクラス定義内にネストされた import に到達できるか確認してください。
