First up, administrivia. I’ve taken the extraordinary measure of editing your post to include the text inline. The “invalid characters” error you’re seeing was caused by the DevForums spam checker, which doesn’t like the word GOLF-OSCAR-ALPHA-LIMA. Don’t ask me why or I’ll start to whimper.
With regards your technical question, iOS does not include a built-in Python interpreter. If you want to run Python scripts, you’ll have to build a Python interpreter into your app. It’s perfectly possible to do this but I wouldn’t characterise it as easy.
If you decide to go down this path make sure you understand clause 2.5.2 of the App Store Review Guidelines.
Share and Enjoy
