Hi,

I am using FME Desktop 2017 and would like to know if there is a way to get a list that I have generated in my FME Workflow, into the PythonCaller, in a similar way to how you use 'getAttribute' function feature.getAttribute(x) to get a normal attribute into the PythonCaller.

Thank you for your help in advance.

For simple and compound lists you can just use

 

 

feature.getAttribute('list{}') or feature.getAttribute('list{}.x')

 

 

For nested lists you need to loop through the parent list to get the sublists.

Hi @aquamarine,

I created a Workspace that show the print values from a List ( _list{}.names ) in Log file using the PythonCaller:

Thanks,

That's exactly what I needed!

 

Thank you @jdh

If you inspect the features prior to the PythonCaller, does every feature have a value for _list{0}.Name?

 

 

You can try adding "if Nombres:" just prior to the for loop, so that there is no python exception if there list doesn't exist.

There seems to be some white space at the end of the _list{}.Name attribute.
