Beginner Developer: Python extension

Hi, im trying to create a python extension,

i tried following both java and python tutorials with no luck in the last few days - in the end node could not be recognised and ive decided to just give up on using IDE - just don’t want to burn any more time playing with a setup, just want to get on with the logic even if debugging is gonna be harder.

My question is - could someone advise what would be bare minimu files needed in \AppData\Local\Programs\KNIME\plugins\ path to have a plugin with one input, one output and python pandas in the middle? I just want to modify .py file logic, change icon and node name.

Are there any simple existing python nodes that i could use as a starting point that you could recommend looking at?
