Objectives

• Doing more with lists/dictionaries and introducing files.

Overview

• This will extends the previous lab to allow the user to display the resulting story with several potential "dynamic" modifications to their input.

Instructions

1. You should first create two files, one for the story template and one for the list of words.
2. Your program should read a "story template" and "word dictionary" from input files and write the output to a file to the screen.
   • The filenames and "conversion type" (see below) should be read from the "command line" when the program is launched.
   • For example:
     LAB4.py 1 story_template.txt input_words.txt

3. If the user launched the program without the correct parameters, a usage message should be shown (such as):
   • USAGE: LAB4.py <CONVERSION> <STORY_TEMPLATE> <INPUT_DICTIONARY>
     CONVERSION: 1 for UPPER CASE, 2 for LOWERCASE, etc…

Conversion Types (of just your input words, not the whole story):

1. 1. All UPPER CASE
   2. All lower case
   3. All Capitalized Case
   4. As entered (i.e., no changes)

NOTES:

• For more information on strings:
• • See http://www.diveinto.org/python3/strings.html
  • And specifically http://www.diveinto.org/python3/strings.html#common-string-methods for manipulations you can perform on strings.
• For more information on files:
• • • Writing: http://www.diveintopython3.net/files.html#writing
    • Reading one line at a time: http://www.diveintopython3.net/files.html#for
  • • • (The Sample I provided reads the entire file into memory. Though this is fine for small files, a very large file would be better processed one line at a time.)
• Remember: You can make up your own story, or just grab a short piece of text from somewhere and edit it into your program, deleting the words you intend on filling in with your own. But In the interest of Academic Integrity, be sure to cite the source of any text you choose to grab!

Example input files:

Story file:

I have a dog named {PETNAME} who barks a lot
and loves to {ACTIVITY} every day.

Words dictionary:

PETNAME=Spot
ACTIVITY=Bark

Submit

• Your final Python program .py file and associated input files.
• 1. Remember it should be able to run as a "command-line" application.
  2. Please call your program LAB4.py and be sure to include your name in the program comments.
