Hi @Anonymous, sorry I wasn't more clear. I was assuming (maybe wrongly) that the Python folder on your desktop contains version 2.7. If it doesn't (if it's Python 3 for instance) you would need to install Python 2.7 somewhere. You don't need to add it to your path, PAD just needs to be able to find the 2.7 modules/libs so PAD's IronPython can import from there.
Here's my code in the Action.
import sys
sys.path.append(r"c:\Python27\Lib")
import getpass
machineUserName = getpass.getuser()
print machineUserName
Here is what you'll have to put in (changing "JackMelvin" to what I can't read to what it is in the actual path):
import sys
sys.path.append(r"C:\Users\JackMelvin\Desktop\Python\Mods")
import getpass
machineUserName = getpass.getuser()
print machineUserName
You might look in that folder to make sure 'getpass.py' is in there.
