Step #1: learn about dictionaries[edit]

Time to practice looking things up! Use your favorite search engine to learn about another useful Python container type called a dictionary. Answer these questions:

  1. How do you create a new dictionary?
  2. How do you replace items in a dictionary?
  3. If you have a dictionary
    flavors = {"Adam": "vanilla", "Jessica": "chocolate"}
    and execute the code
    flavors["Adam"] = "rum raisin"
    what does flavors now look like?
  4. What are 3 examples of when using dictionaries would be a good idea?

Step #2: learn about modules[edit]

Time to practice looking things up! Use your favorite search engine to learn about modules. Answer these questions:

  1. What does import random do?
  2. After reviewing https://docs.python.org/2/library/random.html, how would you select a random item from a list?

Step #3: Review the state capitals quizzer[edit]

Review a useful script synthesizes a number of useful concepts that we've covered.

  1. Download the script state_capitals.py and save it to your Desktop. Be sure to save it as a .py file.
  2. Open the script in your text editor.
  3. Read through the script. Think about these questions:
    • Why do we use a dictionary to store the states and capitals?
    • What is the purpose of the variable i in the for loop?
    • What is the purpose of the input function?
    • Think about one way that you could extend the script to make it more useful. How would you make that change in code?
