cirq.qid_shape

Returns a tuple describing the number of quantum levels of each qubit/qudit/qid val operates on.

cirq.qid_shape(
    val: Any, default: TDefault = RaiseTypeErrorIfNotProvided
) -> Union[Tuple[int, ...], TDefault]

Used in the tutorials
Qudits

Args
`val`	The value to get the shape of.
`default`	Determines the fallback behavior when `val` doesn't have a shape. If `default` is not set, a TypeError is raised. If default is set to a value, that value is returned.

Returns
If `val` has a `_qid_shape_` method and its result is not NotImplemented, that result is returned. Otherwise, if `val` has a `_num_qubits_` method, the shape with `num_qubits` qubits is returned e.g. `(2,)*num_qubits`. If neither method returns a value other than NotImplemented and a default value was specified, the default value is returned.

Raises
`TypeError`	`val` doesn't have either a `_qid_shape_` or a `_num_qubits_` method (or they returned NotImplemented) and also no default value was specified.
