def METHOD_NAME(self, p):
    r"""
    This method customizes the string representation of the basis
    element indexed by ``p``.
    In this example, we just return the string representation of
    ``p`` itself.
    EXAMPLES::
        sage: A = FiniteDimensionalAlgebrasWithBasis(QQ).example()
        sage: A.one()
        x + y

    return str(p)
