SetsWithPartialMaps
(s=None)¶ Bases:
sage.categories.category_singleton.Category_singleton
The category whose objects are sets and whose morphisms are maps that are allowed to raise a ValueError on some inputs.
This category is equivalent to the category of pointed sets, via the equivalence sending an object X to X union {error}, a morphism f to the morphism of pointed sets that sends x to f(x) if f does not raise an error on x, or to error if it does.
