cirq.mul

cirq.mul(lhs: Any, rhs: Any, default: Any = ([], )) → Any[source]

Returns lhs * rhs, or else a default if the operator is not implemented.

This method is mostly used by pow methods trying to return
NotImplemented instead of causing a TypeError.
Parameters:
  • lhs – Left hand side of the multiplication.
  • rhs – Right hand side of the multiplication.
  • default – Default value to return if the multiplication is not defined. If not default is specified, a type error is raised when the multiplication fails.
Returns:

The product of the two inputs, or else the default value if the product is not defined, or else raises a TypeError if no default is defined.
Raises:

TypeError – lhs doesn’t have __mul__ or it returned NotImplemented AND lhs doesn’t have __rmul__ or it returned NotImplemented AND a default value isn’t specified.
