Finite combinatorial classes

class sage.combinat.finite_class.FiniteCombinatorialClass(l)

Bases: sage.combinat.combinat.CombinatorialClass

INPUT:

• l a list or iterable

Returns l, wrapped as a combinatorial class

EXAMPLES:

sage: F = FiniteCombinatorialClass([1,2,3])
sage: F.list()
[1, 2, 3]
sage: F.cardinality()
3
sage: F.random_element()
1
sage: F.first()
1
sage: F.last()
3

cardinality()

EXAMPLES:

sage: F = FiniteCombinatorialClass([1,2,3])
sage: F.cardinality()
3

keys()

EXAMPLES:

sage: F = FiniteCombinatorialClass([1,2,3]) sage: F.keys() [0, 1, 2]

list()

TESTS:

sage: F = FiniteCombinatorialClass([1,2,3])
sage: F.list()
[1, 2, 3]
