Interesting/surprising/strange random poems gathered from the class
Here is a sample of what the programs generated...
- Kevin Devine usually listens to Manchester Orchestra at home every Sunday.
- Man silently dreams 'neath the old pear tree at twilight
- Our neighbor invariably does cartwheels at the store every day
- Goat farmer slowly likes frolicking in the Sahara as often as possible
- My math professor usually sings at home every Sunday.
- Professor Thiebaut eats sweet oranges deliciously with bears on early mornings
- Chuck Norris graciously bosses me around to infinity and beyond at night.
- Jackie Chan savagely munches on cookies on TV during school
- Flying Spaghetti Monster viscously lectures on the roof before class.

# This is a program that creates lists of subjects, adverbs, verbs, locations and times
# and uses random list elements to create a number (inputted by user) of random poems
#
# Example of user interaction:
# Welcome to Random Poems of the Day!
# How many poems would you like me to generate for you? 2
#
# Here are your 2 poems:
#
# Kevin Devine usually sings in Talbot House last at night.
# My math professor never loves pizza underwater all the time.
from random import randrange
def main():
print( "Welcome to the Random Poems of the Day!" )
# ask user how many poems to print
numberPoems = eval(input( "How many poems would you like me to generate for you? "))
print()
# create lists of subjects, adverbs, verbs, locations, times
subjects = [ "Kevin Devine", "The record player", "iTunes", "My math professor", "Amy Poehler" ]
adverbs = [ "usually", "sweetly", "quietly", "never" ]
verbs = [ "sings", "eats pizza", "loves pizza", "listens to Manchester Orchestra" ]
locations = [ "at home", "in Talbot House", "underwater" ]
times = [ "all the time", "late at night", "at sunrise and sunset", "every Sunday" ]
# create a collection of the lists that loops will reference
words = [ subjects, adverbs, verbs, locations, times ]
print( "Here are your", numberPoems, "poems:")
print()
# outer loop ensures that desired number of poems is printed
for j in range( numberPoems ):
for i in words:
# pick a random number from the length of the list
randomIndex = randrange( len(i) )
#print word in list that corresponds to that number, followed by a space
print( i[ randomIndex ], end=" " )
# deletes the last space that was printed and inserts a period
# goes to new line for next poem

Forms
# hw3b.py
# 111a-bz
# Yingtong Ding
# 111a-by
# Jenny Wang
# The program prompts the user
# for the width of the form, the name
# of the string to display in the box
# under the date box, the number of candidate
# names and the names of the candidates
# for which forms will be generated
# Then the user enters the names and the program
# outputs the forms, one per name.
#
# LIMITATIONS:
# ------------
# The limitations of this program: The width of the form cannot be smaller than
# the length of the names plus the length of the date box plus one.
# The length of the extra label box under the date box cannot be longer than the
# length of the date box.

Money
A very short and concise solution for this problem is provided by Kate.
# hw3d.py
# 111a-ah
# Kate Aloisio
#
# This program asks the user how much money she wants
# to withdraw from the cash machine, and will output
# how many 20, 10, 5, and 1 dollar bills she will get in return.
#
def main():
# greeting
print("\nWelcome to the Virtual Cash Machine\n")
# how much money?
amount = eval( input( "How much money do you need today? " ) )
# break down of bills
print( "\nPlease lift your keyboard and find: ", end=" ")
bills = [ 20, 10, 5, 1 ]
for bill in bills:
count = amount//bill
amount = amount%bill
line = "%2d $%d-bill(s)" % (count, bill)
print( line + "\n" + " "*36, end=" " )
# closing
print( "\nThank you for your transaction!" )
