Any help is appreciated. Thank you

Hi @sandhya.b

Welcome to our UiPath Forum! :slight_smile:

Maybe this tutorial will help you:

It contains a very simple guide with screenshots and steps to follow on how to use Python scripting in UiPath Studio :slight_smile:

Hello @soundappan.prabu
As you have mentioned its working in IDE, can you please confirm you have passed the arguments to the python script in uipath?

Also please share the error if any.


No, through python IDLE only! A simple function working fine with python scope of UIpath! when passing one than one parameter then the problem rises.!
