Random spambot

spam.py

import re
import random

def random_keyword(match):
    keywords = match.group(1).split('|')
    return random.choice(keywords)

r = re.compile(r'{([^}]+)}')

with open('comment.txt') as f:
    text = f.read()

output = re.sub(r, random_keyword, text)

print(output)

Bonus extra readable version:

import re,random
with open('comment.txt')as f:print(re.sub(r'{([^}]+)}',lambda x:random.choice(x.group(1).split('|')),f.read()))
