In addition to the concepts below, you should also know the concepts from Quiz 1, Quiz 2, and Quiz 3. Many of the earlier concepts -- especially functions -- are fundamental to what we've been studying recently.

You should be able to define the following terms:

• definite loop
• indefinite loop
• top-down design
• unit testing
• bottom-up development
• stubbed-out function
• pseudocode
• file variable
• newline character
• python list
• python dictionary
• key-value pairs

You should understand and be able to use the following Python concepts:

• while (indefinite) loops
• file methods like open() and read()
• definite loops on a file
• string methods like strip(), isupper(), islower(), and split()
• the list append() method
• dictionaries, including
  • the empty dictionary
  • adding a key-value pair to a dictionary
  • accessing the value for a key in the dictionary
  • dictionary methods like keys() and values()
• the in boolean operator for lists, strings, and dictionaries
• You should also be able to write basic operations using lists, files, and dictionaries, such as
  • read and print all lines in a file
  • read all lines in a file and store as a list
  • print all key-value pairs in a dictionary

Practice problems:

1. Write a for loop that prints out all even numbers from 2 to 20.
2. Write a while loop that prints out all even numbers from 2 to 20.
3. Write a program that reads in the following data from a file and stores the data in a python dictionary:

   lisa 98
   betsy 100
   charlie 91
   jeff 82
   amanda 88
   jon 86
   andy 77
   

4. Given any specific definite (for) loop, write an indefinite (while) loop that performs the same computation.
