I want to call 'n' which is the input number followed by a string.

I've been putting it like this: (n 'string') but it is wrong. How do I write it?

if that didn't make sense, i'm trying to title my plot.
pl.title(n, 'circles') where n is an input number

Nevermind, I did a quick google search all I had to do was something like:
(str(n)+"circles")
