# let's have the computer tell us "hello world!"
# Remember, a computer program is a set of instructions we tell the computer what to do.

print("Hello World!")

# When we run the program, Python returns the string inside the parentheses
# a string is just any series of letters, numbers, or symbols. Think of it as a line of text.

# A simple program to have the computer take input from the user... Or so it seems!

message = ("Tell me something, and I will repeat it back to you: ")
print(message)

# Now, the message is printed, but the user cannot type anyhting in!
# What function do we need to add and where?

# Data is at the heart of most computation. Remember, the earliest computers helped people
# "store" their counts - tally sticks. Today's computer systems are excellent data storage
# systems. So, it makes sense to learn some about how computer programs store and retrieve data.

# The following is a gist of gist by Wray.
# We know all about loops and conditionals, so let's create a simple search by first name.

# Here's where we define our function
def find_contact_by_first_name(first_name):
    for contact in contacts:                  # and here is our for loop found within the function's block of code
        if contact[0] == first_name:
            return contact

contact = find_contact_by_first_name("John")

# looking at our previous example of a dicitonary of similar objects
favorite_languages = {
    'jen': ['python', 'ruby'],
    'sarah': ['c'],
    'edward': ['ruby', 'go'],
    'phil': ['python', 'haskell'],

# you can store different kinds of information about one object in a dictionary,
# you can also use a dictionary to store one kind of information about many objects.

# Let's say we wanted to poll a number of people and ask them what their favorite programming language is.
# A dictionary can be useful for storing the results of a simple poll:

# store info about a pizza being ordered
# list in a dictionary
pizza = {
  'crust':'thick',
  'toppings': ['mushrooms', 'pepperoni', 'extra cheese'],
}

# summarize the order:

# Rather than typing from scratch (only ~50min of lecture available), students will 
# each have these lines of code for a basic snake game using pygame.
# Lines will either be omitted or commented out
# students will follow along via the instructor/whiteboard; either typing in a few lines of code where its needed
# and/or students will uncomment lines of code that carry out specific feature related to the objectives
