Question

Is there a way to convert a given Python abstract syntax tree (AST) to a source code?

Here is a good example of how to use Python's ast module, specifically a NodeTransformer. I was looking for a way to convert the resulting AST back to source, so the changes can be inspected visually.

Answer 1

The Python source tree contains an implementation of this: unparse.py in the Demo/parser directory: https://github.com/python/cpython/blob/master/Tools/parser/unparse.py
