== Goal #1: using modules ==
(Estimated completion time: 15 - 30 minutes)
To get some more practice with the <code>random</code> module, we're going to read, run, and extend some Python scripts that use this module.
For each of the following Python scripts, please do the following:
<ol>
<li>Download the script and save it to your Desktop. Be sure to save it as a <code>.py</code> file.</li>
<li>Open the script in your text editor.</li>
<li>Read through the script. Answer these questions:
<ul>
<li>Overall, what does this script do?</li>
<li>What variables and data types are used? Where are the strings, integers, and floats?</li>
<li>What functions from the <code>random</code> module are used, and why?</li>
</ul>
</li>
<li>Once you have a good sense of what the script does, open a terminal, navigate to the directory where you saved the script, and run it. Does it do what you expected?</li>
</ol>
<b>Here are you scripts to read and run</b>. Have fun with them!
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit4/die.py die.py]
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit4/password_generator.py password_generator.py]
For <code>die.py</code>, how would you change the program to simulate rolling 2 dices?
For <code>password_generator.py</code>, how would you generate a password that was, instead of a fixed 10 characters long, a random length between 10 and 14 characters?
== Goal #2: reading from files ==
(Estimated completion time: 15 - 30 minutes)
To get some more practice with reading from files, we're going to read, run, and extend some Python scripts.
=== Countries example ===
Here are the country names text file and Python script from the lesson:
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit5/countries.txt countries.txt]
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit5/countries.py countries.py]
Please download both files and save them to your Desktop. Review <code>countries.py</code>, make sure you understand it, and then run it!
Then, <b>add code to the file to answer the following questions</b>:
* What are all of the countries that end in "land"?
* What is the shortest country name?
=== Wordplay example ===
Here are two new files. The first, <code>sowpods.txt</code>, is the official Scrabble wordlists we'll use for our Scrabble cheater. The second is a Python script that uses data from <code>sowpods.txt</code> to find weird and interesting words:
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit5/sowpods.txt sowpods.txt]
* [http://web.mit.edu/jesstess/www/SkillsharePython/Unit5/wordplay.py wordplay.py]
Please download both files and save them to your Desktop. Open <code>wordplay.py</code>, see if you can guess what it does, and then run it!
Then, using the existing code as a template, <b>add code to the file to answer the following questions</b>:
* What are all of the words that contain "VV"?
* What are all of the words that contain "Q" without a "U"?
* What are all of the words that contain all of the vowels and Y, ("A", "E", "I", "O", "U", "Y") in any order?
What other weird words can you find?
