Is there a way to get multiple inputs into a python snippet?
Cheers,
Steve.
Currently - no.
The only way I can think of, is to export the tables and to transfer their file paths to a python snippet. But then the python script has to handle the data import...
OK, thanks.
A bit tedious to have to do it this way - multiple inputs as a feature request then?
Cheers,
Steve.
I'll put it into the issue list, yes. As each node has to set a fixed number of (optional) inputs: How many would have been suitable for your problem?
Hi,
Two inputs would have been OK for what I'm doing - but no doubt I will need more in future!
Cheers,
Steve.
Can you use the 'cross joiner' node on the two input tables to effectively combine them into a single table? If you want to separate the columns apart again later, you could add a prefix to the column names using the 'column name (regex)' node before the cross join.

I used Python Snippet node to load a data table with 25 columns, and configure this node as "pyOut = kIn", I got the following errors:
ERROR Python Snippet 0:23 Traceback (most recent call last):

Who knows how to fix this problem?
