From 6a877cccbce2b700a0195093f705b60a5a246624 Mon Sep 17 00:00:00 2001 From: cxzhong Date: Mon, 20 Oct 2025 17:08:41 +0800 Subject: [PATCH 1/4] Fix doctests for Python 3.14: Update unhashable TypeError messages to use ellipsis pattern Python 3.14 changed the format of TypeError messages for unhashable types from: TypeError: unhashable type: 'list' to: TypeError: cannot use 'list' as a dict key (unhashable type: 'list') Updated all doctests to use ellipsis pattern (e.g., 'TypeError: ...unhashable...') to match both old and new error message formats. Modified 25 files across multiple modules including: - Documentation (tutorial-programming-python.rst) - Graph modules (graph.py, generic_graph.py, c_graph.pyx, bipartite_graph.py) - Combinatorics (diagram_algebras.py, finite_state_machine.py) - Sets (disjoint_set.pyx, set.py) - Geometry (polyhedron modules) - Structure (sage_object.pyx, unique_representation.py) - Matrix (matrix0.pyx) - Misc utilities (weak_dict.pyx, cachefunc.pyx) - P-adic rings (qadic_flint_*.pyx, padic_ZZ_pX_CR_element.pyx) - Polynomials (multi_polynomial.pyx, polynomial_element.pyx) - Modules (indexed_element.pyx, tutorial_free_modules.py) - Topology (simplicial_complex.py) --- .../tutorial-programming-python.rst | 4 ++-- src/sage/combinat/diagram_algebras.py | 2 +- src/sage/combinat/finite_state_machine.py | 6 +++--- src/sage/geometry/polyhedron/base4.py | 2 +- src/sage/geometry/polyhedron/base_mutable.py | 2 +- src/sage/graphs/base/c_graph.pyx | 4 ++-- src/sage/graphs/bipartite_graph.py | 2 +- src/sage/graphs/generic_graph.py | 3 +-- src/sage/graphs/graph.py | 8 +++----- src/sage/matrix/matrix0.pyx | 4 ++-- src/sage/misc/cachefunc.pyx | 2 +- src/sage/misc/weak_dict.pyx | 12 ++++++------ src/sage/modules/tutorial_free_modules.py | 2 +- src/sage/modules/with_basis/indexed_element.pyx | 2 +- src/sage/rings/padics/padic_ZZ_pX_CR_element.pyx | 2 +- src/sage/rings/padics/qadic_flint_CA.pyx | 2 +- src/sage/rings/padics/qadic_flint_CR.pyx | 2 +- src/sage/rings/padics/qadic_flint_FP.pyx | 2 +- src/sage/rings/polynomial/multi_polynomial.pyx | 2 +- src/sage/rings/polynomial/polynomial_element.pyx | 4 ++-- src/sage/sets/disjoint_set.pyx | 2 +- src/sage/sets/set.py | 2 +- src/sage/structure/sage_object.pyx | 2 +- src/sage/structure/unique_representation.py | 4 ++-- src/sage/topology/simplicial_complex.py | 2 +- 25 files changed, 39 insertions(+), 42 deletions(-) diff --git a/src/doc/en/thematic_tutorials/tutorial-programming-python.rst b/src/doc/en/thematic_tutorials/tutorial-programming-python.rst index 2fa542d0c5e..0e60f0f3ab8 100644 --- a/src/doc/en/thematic_tutorials/tutorial-programming-python.rst +++ b/src/doc/en/thematic_tutorials/tutorial-programming-python.rst @@ -87,7 +87,7 @@ The *standard types* are :class:`bool`, :class:`int`, :class:`list`, sage: set([ [1], [2] ]) Traceback (most recent call last): ... - TypeError: unhashable type: 'list' + TypeError: ...unhashable type: 'list'... * A *dictionary* is an association table, which associates values to keys.
