From 00e4276855fa694c4f658033f7020b418ac49b15 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jo=C3=A3o=20S=2E=20O=2E=20Bueno?= Date: Sun, 29 Sep 2024 03:08:23 -0300 Subject: [PATCH] Adapts to Python 3.13 - some of the functions in the unstable _interpreters had changed semantics, as well as some behavior (errors in .run_string no longer raise an exception, for example) This commit fixes code so that it works in build 3.13:50a595b --- src/extrainterpreters/__init__.py | 22 ++++++++++++++++++--- src/extrainterpreters/memoryboard.py | 22 +++++++++++++-------- src/extrainterpreters/queue.py | 16 +++++++-------- src/extrainterpreters/simple_interpreter.py | 7 ++++++- tests/test_basic.py | 10 +++++----- tests/test_boards.py | 1 -
