### method `count`
```python
count(
circuit_feedback: CircuitCompilationFeedback,
operations: Set[PrimitiveOperation]
) → int
```
Count the amount of specified operations in the program.
**Args:**
operations (Set[PrimitiveOperation]): set of operations used to filter the statistics
**Returns:**
int: number of specified operations in the program
---
### method `count_per_parameter`
```python
count_per_parameter(
circuit_feedback: CircuitCompilationFeedback,
operations: Set[PrimitiveOperation],
key_types: Set[KeyType],
program_info: ProgramInfo
) → Dict[ForwardRef('Parameter'), int]
```
Count the amount of specified operations in the program and group by parameters.
**Args:**
operations (Set[PrimitiveOperation]): set of operations used to filter the statistics
key_types (Set[KeyType]): set of key types used to filter the statistics
program_info (ProgramInfo): program info required for grouping by parameters
**Returns:**
Dict[Parameter, int]: number of specified operations per parameter in the program
---
