Is there a way to generate more useful error messages that indicate a line number or some way to know what's generating the error? It's really painful to debug things when I have to comment out a line, wait 30-60s for a backtest to run, comment out a different line, rinse/repeat, etc.

Python errors are obtuse

Sorry about the lack of errors Karl. We'll work on improving them ASAP --
We just fixed the slow-backtesting issue -- you should get backtest results within 10 seconds now.

Thanks for the response! Definitely seems faster now. I think a little would go a long way (line numbers). I think once you are super familiar with the syntax and how all the classes work, it's probably not as important, but trying to learn the various nuances of the QC classes with little documentation and non-specific error messages has been a challenge :).

Hi Mikko,
When there is a runtime error due an exception in the python code, the error message provides the line number. Besides, we provide an efficient way for debugging. Here is the instruction.
Hope this help!
