y
__and__ function returns the intersection of the Sets x and y. This can be done equivalently with x and y.
__or__ function returns the union of the Sets x and y. This can be done equivalently with x or y.
__xor__ function returns the symmetric difference of the Sets x and y. This can be done equivalently with x ^ y.
__sub__ function returns the set difference of the Sets x and y. This can be done equivalently with x - y.
The following interactive session illustrates the use of these operators:
>>> import maple
>>> import maple.namespace
>>> S1 = maple.execute('{3,4,5};')
>>> S2 = maple.execute('{3,4,sqrt(2)};')
>>> S1 and S2
{3,4}
>>> S1 or S2
{3,4,5,sqrt(2)}
>>> S1 ^ S2
{5,sqrt(2)}
>>> S1 - S2
{5}
>>> S2 - S1
{sqrt(2)}
