Python export from ModelBuilder Error- IndexError: list index out of range

Question

Please bear with me, I'm new to using Python. I am trying to create a scheduled task to run a model from ModelBuilder weekly. First, I exported my model from ModelBuilder as a Python script (to verify, this models runs when manually prompted in Modelbuilder). Then, I wanted to verify the model ran as a Python script, so I ran the module using IDLE, however, I keep getting an error: Traceback (most recent call last): File "\\gis\\Scripts\.py", line 24, in = sys.argv[1] IndexError: list index out of range I have searched other forums with little taken from them as I cannot view line 24. I can only view the sys.argv[1] as: = sys.argv[1] if == '#': = "" # provide a default value if unspecified Please, if someone can help, offer your assistance!

I know this is an old thread, but why not add this info to it: With no argument this would still fail, as with no arguments sys.argv[1] is still out of range. Better a try except block: try: event_name = sys.argv[1] except: event_name = raw_input("enter an event name: ")‍‍‍‍‍‍‍‍

I think you get this error because you cannot run a script from IDLE with any arguments. If you were to call this script from the command line,

eg >>>> myscript.py argument1

then argument1 gets parsed as sys.argv[1] and it would probably run, likewise from model builder.

For testing you could put in some code like this:if not sys.argv[1]:
    event_name = raw_input('Enter an event name')

that would catch the possibility of there not being an argument and allowing you to enter it at run time
