Random quote from array

I recently starting my introduction into Python about 1-2 weeks ago and have been loving the language, I've made a few projects and am having trouble on a specific one. I want to write a program that automatically prints out quotes and things to lighten up your day and I'm having trouble getting a random quote from an array.

the array looks like: quotes = ['You are cool', 'etc', 'etc'] and I want to find a random string in that array ^ anyone know how?
