How to walk the AST produced by parse or parse_file?

Closed this issue 4 years ago · 1 comments

I just don't know the meaning that the second param named "callback_object" in function "visit" of parser.py in this module. How can I leverage this function to walk the AST produced by parse or parse_file? Or maybe other more useful methods to apply to this.

Hi @rookiekuan,

There are some examples on how to manually walk the AST in the README and the main file. Another option is to create your own visitor.

hope that helps.
cheers,
