Hi everyone, I’m trying to work with datasketches in Python. I’m having a bit
of trouble understanding the interface for TupleSketch. I creating a custom
policy which updates a counter, and created an update_tuple_sketch like so:
```
from _datasketches import TuplePolicy
import datasketches
class MyCounterPolicy(TuplePolicy):
def __init__(self):
TuplePolicy.__init__(self)
def create_summary(self) -> int:
return int(1)
def update_summary(self, summary: int, update: int) -> int:
print(summary, update)
summary += update
return summary
def __call__(self, summary: int, update: int) -> int:
summary += update
return summary
sketch = datasketches.update_tuple_sketch(MyCounterPolicy(), lg_k=12)
sketch.update(1, 2)
```
The print() statement in update_summary confirms that it is called with the
appropriate arguments. So, once I’ve called sketch.update, how do I access the
summary information, which should be a single in equal to 3?
