title: File encryption and decryption
body: <p>So I need pseudo code for this assignment and I have no idea where to start. I am not trying to mooch off you guys, I would just like some guidance on where to start! </p>
  
  <p>Write a program that uses a dictionary to assign “codes” to each letter of the alphabet. </p>
  
  <p>For example:</p>
  
  <pre><code>codes = { 'A' : '%', 'a' : '9', 'B' : '@', 'b' : '#', etc...}
  </code></pre>
  
  <p>Using this example, the letter <code>A</code> would be assigned the symbol <code>%</code>, the letter <code>a</code> would be assigned the number <code>9</code>, the letter <code>B</code> would be assigned the symbol <code>@</code>, and so forth.</p>
  
  <p>The program should open a specified text file, read its contents, and then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file.</p>
  
  <p>Write a second program that opens an encrypted file and displays its decrypted contents on the screen.</p>
