py2py3-converter

1. Introduction

py2py3-converter is an OpenClaw skill that automatically converts legacy Python 2 code to modern Python 3 syntax. It handles the most common migration patterns, generates compatibility reports, and creates unit tests for the converted code.

Python 2 reached end-of-life on January 1, 2020, yet many codebases still contain Python 2 code. This skill automates the tedious work of manual migration, reducing human error and accelerating the upgrade process.

Conversion Logic

The converter handles these Python 2 → 3 transformations:

• print statements → print() function calls
• raw_input() → input()
• xrange() → range()
• unicode() → str()
• basestring → str
• long type → int
• dict.has_key(k) → k in dict
