How To Install python3-astor on Ubuntu 18.04
Introduction
In this tutorial we learn how to install python3-astor on Ubuntu 18.04.
What is python3-astor
python3-astor is:
astor is designed to allow easy manipulation of Python source via the AST.
There are some other similar libraries, but astor focuses on the following areas:
Round-trip back to Python via Armin Ronacher’s codegen.py module:
- Modified AST doesn’t need linenumbers, ctx, etc. or otherwise be directly compileable
Dump pretty-printing of AST
- Harder to read than round-tripped code, but more accurate to figure out what is going on.
- Easier to read than dump from built-in AST module
Non-recursive treewalk
- Sometimes you want a recursive treewalk (and astor supports that, starting at any node on the tree), but sometimes you don’t need to do that. astor doesn’t require you to explicitly visit sub-nodes unless you want to:
- You can add code that executes before a node’s children are visited, and/or
- You can add code that executes after a node’s children are visited, and/or
- You can add code that executes and keeps the node’s children from being visited (and optionally visit them yourself via a recursive call)
- Write functions to access the tree based on object names and/or attribute names
- Enjoy easy access to parent node(s) for tree rewriting
