How to: Add exception traceback

It can be useful to log and pass back the exception description and traceback associated with your calculation.

The snippet below shows how we can use a try-except statement to add exception information to the ArupComputeResult object returned by the calculation:

import traceback # built-in module

def divide(dividend: float, divisor: float) -> ArupComputeResult:
    acr = ArupComputeResult()

    try:
        quotient = dividend / divisor
        acri = ArupComputeResultItem()
        acri.symbol = "quotient"
        acri.value = quotient
        acr.arupComputeResultItems.append(acri)

    except Exception:
        acr.errors.append(traceback.format_exc())  # add traceback to AC errors
        return acr

    return acr
