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.
The Python source tree contains an implementation of this: unparse.py in the Demo/parser directory
Editor’s note: With the introduction of
ast.unparse()in Python 3.9, unparse.py has been removed, so the above link has been updated to point to 3.8.
