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

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.

def main():
    print('''
-------------------------------
 WELCOME TO THE FORM GENERATOR
         P R O G R A M
-------------------------------''')
    print()
    # get data from the user
    width = eval(input("What is the width of the form? "))
    
    # get name of the extra label under the date from the user
    label = input("What is the label of the box under the date? ")
    
    # get the number of candidates from the user
    num = eval(input("How many candidates do you have? "))
    
    # get names of the candidates from the user
    names = []
    for i in range(num):
        names.append (input("Candidate "+str(i+1)+" : "))
    print()


    print()
    # compute various quantities

    dateLine   = '| date:        |'
    dateLine2  = '+--------------+'
    labelLine  = '| '+label+' '*(len( dateLine )-3-len(label))+'|'
    noSpacesB4 = width - len( dateLine )-1

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!" )

# This program the user for the number of different

# Also, the box will not be formatted correctly if the
# user gets more than 99 bills in any of the denominations.
