Circuit.count

Circuit.count(op)[source]

Count the number of times op occurs in the circuit.

Parameters:: op (Operation | Gate) – The operation or gate to count.
Raises:: ValueError – If op could not have been placed on the circuit due to either an invalid location or gate radix mismatch.

Examples

>>> from bqskit.ir.gates import HGate
>>> circ = Circuit(1)
>>> op = Operation(HGate(), [0])
>>> circ.append(op)
>>> circ.count(op)
1
>>> circ.append(op)
>>> circ.count(op)
2
