Which method can you use in the PythonCaller to create an FME list from a Python list?

• A. fmeobjects.FMEFeature.buildAggregateFeat
• B. fmeobjects.FMEFeature.setAttribute()
• C. fmeobjects.FMEFeature.getAttribute()
• D. fmeobjects.FMERegex.findlist

Answer: (B)

In the PythonCaller, to create an FME List from a Python list you assign the Python list to an attribute using the setAttribute method on the FMEFeature. When you call feature.setAttribute('yourList', pythonList), FME converts the Python list into an FME List attribute, preserving the items. The other options don’t create lists: building an aggregate feature is about combining features, retrieving an attribute reads data, and the regex findlist is unrelated to FME list creation.
