import random

import sys

articles = ["the", "a", "another", "her", "his"]

"laughed", "walked"]

adverbs = ["loudly", "quietly", "quickly", "slowly", "well", "badly",

"rudely", "politely"]

lines = 5

if len(sys.argv) > 1:

try:

temp = int(sys.argv[1])

if 1 <= temp <= 10:

lines = temp

else:

print("lines must be 1-10 inclusive")

except ValueError:

print("usage: badpoetry.py [lines]")

while lines:

article = random.choice(articles)

subject = random.choice(subjects)

verb = random.choice(verbs)

if random.randint(0, 1) == 0:

print(article, subject, verb)

else:

adverb = random.choice(adverbs)

print(article, subject, verb, adverb)

lines -= 1
