I am working in a python node, and created a list of strings that I will be using in the next node (attrib wrangler).
maybe I can store it in a different way?

Hi,

yes you can use array attribute types, which are supported in the VEX context. For example an array of string is supported to be exported back from python. The only thing you have to do, is adding and setting a global attribute.
Check attached file example for the syntax.

Yes,

it seems that geo.addAttrib can't handle strings. If I put an array into it, it creates as many attributes as array size. For string array it will be empty.

Here is an example that worked for me. 

node = hou.pwd()
geo = node.geometry()

some_list = ["blah","blah"]
geo.addArrayAttrib(hou.attribType.Global, "data", hou.attribData.String, tuple_size=1)
geo.setGlobalAttribValue("data", some_list)
