Shawn and Patrick asked about a TextExpander thing, and then I made it.

TypoTextExpander

#!/usr/bin/env python
# coding: utf-8
import random

# Instructions: this is a TextExpander snippet. Copy and paste all of this (starting with #!/usr and
# ending with "— Shawn") as the content of a new snippet in TextExpander. Then, set the content of the
# snippet to "Shell Script".


# This is the list of sentences. Add as many as you want. Just write sentences.append("your sentence here") on
# a new line and it'll be added to the list.

sentences = []
sentences.append("Good catch. Fixed now. Thanks!")
sentences.append("Whoops. I'm always making mistakes like that. Fixed now.")
sentences.append("Thanks for pointing that out. I've updated the post.")

print sentences[random.randint(0,len(sentences)-1)] + "\n\n— Shawn"
