Hi Chris,

Do you think it would be useful to have a “stop\_on\_error” attribute for the run\_python\_file/run\_python\_string actions?  
I’d probably want to keep this turned on so the experiment would stop on exceptions in python.

Thanks,  
Mark

Hi Mark,

Yes, that seems useful. I’ll add it.

Great - if you’re prioritizing stuff from us, this is probably the highest priority item since we don’t have a good workaround.

Hi Mark,

This is done and will be in tonight’s nightly build. The attribute is called “stop\_on\_failure”.

Great - thanks. Will test.  
I can’t think of a case where I’d want stop\_on\_failure to be NO, so I’d argue for default YES. But perhaps others use it differently.

The default is NO to maintain compatibility with existing experiments.
