Python AST with preserved comments

An AST that keeps information about formating, comments etc. is called a Full Syntax Tree.

redbaron is able to do this. Install with pip install redbaron and try the following code.

import redbaron

with open("/path/to/module.py", "r") as source_code:
    red = redbaron.RedBaron(source_code.read())

print (red.fst())

The ast module doesn't include comments. The tokenize module can give you comments, but doesn't provide other program structure.
