First of all, sorry if this has been asked, but I couldn't find anything, or maybe I just couldn't phrase it right.
I'm writing dialogue as of now, and I'm not quite sure how to call the keys, which are in integer form. I saw similar being used in the documentation, but no matter what way I've tried to call them, it failed.
"dictionary.22" fails, "dictionary.keys()[22]" fails etc. Trying to feed them in a string format, fails.

My question therefore is -- How do I access keys, that happen to be in numeric form?
