Output text

There are a lot of rules about printing text. Here are some basics.

print is the most common command, and followed by ('…')
>print('how cool')
>how cool
Quotes “” or will output ticket. If you want quotes you have to do them in
>'“yes” he said'

>'Isn\'t it great'

To not interpret \ as a line, put r before quotes
