Description
As of now, passing a list, tuple, or set to cartesian_product
returns an AssertionError?.
sage: cartesian_product([[0,1]]) AssertionError: sage: cartesian_product([FiniteEnumeratedSet([0,1])]) The cartesian product of ({0, 1},)
I understand that this function can construct Cartesian products on different categories, so I see why it requires specific types. However, the error message should be more descriptive, especially considering that cartesian_product_iterator([[0,1]])
, CartesianProduct([0,1])
, and permutations([[0,1]])
all work.

Hello,
I propose to close this one as duplicate since with #18411 tuple/list input are automatically converted into
FiniteEnumeratedSet
and set/frozenset converted toSet
