It seems that currently the Python tool is raising a `FileNotFoundError` exception in Python when there is not data incoming on an input connection. I have, for example, a Filter tool before the Python tool and sometimes there is just no data coming to Python tool - as it is intended.
Unfortunately, the Python tools gives my an error message in those cases with this message before the error:
Python (15)Unable to connect to input data (C:\Users\CCEB8~1.HAR\AppData\Local\Temp\3a9bb9672d7abbe6af3176379ae8c3b1\15\4460abb7be83bae8f01b9bf1238a923c.sqlite)
This is only the case when there is no data incoming. In all other cases, the tool works fine.
Since this is not really an error, a way to either catch this before using `Alteryx.read("#1")` or just having `Alteryx.read()` return an empty data.frame (as I would expect it to do) would be appreciated.
