When should we run a python -i. wishlist.py instead of python wishlist.py.

Seems lists don't work under python wishlist.py.

Without the "-i", Python should run your program and exit. When you use it, it will still run the program, but when that finishes it will stay running and take commands from the console as if you had started it without naming a program.

The running of the program should be the same in either case. If you have an issue, you could post your program here in a separate question to get help on it.

It's a good way to continue using the program and playing around after it's run without it executing and finishing.
