Passing Python List into Workflow

[chris.shanor]

I am creating a List of Lists of Strings in Python. The child lists contain names, addresses. Using the Get Python Object activity, how would I use these lists in the workflow. What .NET datatype should I use? I tried using
but that didn’t work. Any help would be appreciated.

Hi @chris.shanor,

Welcome to the community!

In my previous tests, handling return values from one programming language to another ( in this case python to .net ) is always cumbersome. Therefore, I suggest you change the return value to a json string. Here is a post where I given an example.

How can the python packages be installed in uipath?

Hi @sssi How did you solve this? May be others having the same problem can use what you used. Kindly pen it down in this thread. def detect_face(img): You are doing everything right here. But one heads up is converting python return types to .net types can be often clumbersome. What I learnt from expierence is that it is easier to use json string as a return from python. For example, your code could look like: import json import cv2 import os import numpy as np from facenet_pytorch impo…

In short :

import json

def YourFunction():
     YourList = [1, 2, 3]
     return json.dumps(YourList)

Call you YourFunction in UiPath. Desearlize the json string to access the Jsonarray.
