This node executes a snippet/script using Python. The
script for Python can be selected from a snippet
template repository. RGG (
R GUI Generator
) is used to configure the Python code using a graphical
user interface in a way that the user does not need to
know scripting in Python. URL of the template file can
be set in KNIME->Preferences->KNIME->Python Scripting
The input data table from KNIME is converted to a
dictionary and imported into Python as a variable named
"kIn". The output data table is sent back to KNIME as
"pyOut".
Script Editor:
Copy, cut or paste and Python code to the editor and/or
select the columns from your data table. If a template
is loaded used the GUI to adapt the script to the input
data.
Templates:
Select a snippet template from the template repository
(double-click or "Use this template") to use that script
and see the GUI. The description explains what a snippet
does. Then configure the GUI according to your input
data.
Output Options:
Specify the output table to avoid that the node shows a
warning.
IMPORTANT:
TThis node is using Python as backend, make sure that
Python is installed locally or that the node can connect
to the Python server is running somewhere accessible.
Check the node configurations:
KNIME->Preferences->KNIME->Python Scripting.
Further documentation can be found on the
Scripting integration Wiki (Python server)
