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.
