From adf062f7e2655e719f03db3f5bdeda3dd3972e17 Mon Sep 17 00:00:00 2001 From: openhands Date: Thu, 16 Oct 2025 00:45:49 +0000 Subject: [PATCH 1/2] Remove Python 2 compatibility code for Python 3.10+ modernization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit removes all Python 2 compatibility code from the epitran repository: ## Changes Made: ### 1. Replaced unicodecsv with standard csv module (14 files) - Core library files: stripdiacritics.py, space.py, flite.py, xsampa.py, puncnorm.py, reromanize.py - Binary/utility files: connl2engipaspace.py, migraterules.py, isbijective.py, space2punc.py, connl2ipaspace.py, ltf2ipaspace.py - Data processing: count_phones.py - Pattern: import unicodecsv as csv → import csv - File opening: open(file, 'rb') → open(file, 'r', encoding='utf-8') - CSV readers/writers: removed encoding parameter (now handled by file opening) ### 2. Removed unicode() function usage - flite.py: Removed unicode() function definition and 3 function calls - Replaced with native Python 3 string handling ### 3. Removed all __future__ imports (64+ files) - Removed from all Python files in the repository - Common imports: unicode_literals, print_function, etc. - Cleaned up dangling import statement fragments ### 4. Updated setup.py dependencies - Removed subprocess32 conditional dependency for Python < 3.0 - Now targets Python 3.10+ exclusively ## Testing: - ✅ Basic imports work correctly - ✅ Core transliteration functionality verified - ✅ CSV-dependent functionality (XSampa) tested - ✅ Command-line scripts load successfully Total files modified: 65+ files Target Python version: 3.10+ All functionality preserved and tested.
