Everything is working fine when I do python cli.py - get the results I expect:
it works
['okra', '30', '0.10']
You are buying 30 okra for $3.00
However, if I run it in Idle I get
File "/home/louis/Code/cli.py", line 8, in <module>
food = arguments[0]
IndexError: list index out of range
Is this some weakness in idle, if I used VS code wouldn't do this?
You can try and run your script in IDLE's debugger mode and see if it's anything that IDLE ran against and didn't like..
but you're right it could be an IDLE issue if VSC code runs it fine.

Probably you are referring to the course item https://app.itpro.tv/course/introductionprogramming-using-python/reading-command-line-arguments.
When you are using IDLE you can't transmit to the script command line arguments and that's why it fails with the out of range exception. See here https://stackoverflow.com/questions/2148994/when-running-a-python-script-in-idle-is-there-a-way-to-pass-in-command-line-arg
When running VS Code you can run the script in the terminal and also you can setup it up to send default arguments by configuration in case you call it with Run/Debug . See here https://code.visualstudio.com/docs/python/debugging
