# pytket.circuit.OpType

Enum for available operations compatible with the tket {py:class}`Circuit` class.

:::{warning}
All parametrised OpTypes which take angles (e.g. Rz, CPhase, FSim) expect parameters in multiples of pi (half-turns).
This may differ from other quantum programming tools you have used, which have specified angles in radians, or perhaps even degrees.
Therefore, for instance `circuit.add_gate(OpType.Rx, 1, [0])` is equivalent in terms of the unitary to `circuit.add_gate(OpType.X, [0])`
