################ Fibonacci Sequence!
# Hint: You will have to use some variables in this sequence. I've set up the variables for you. 
# Our first number will start with 0 for this sequence
first = 0
second = 1

# Add the first two numbers to a list called fibNumbers.


# Now create a loop that will add the next 15 digits to fibNumbers. 


# Print fibNumbers. The last number should be 987




############### Bonus Exercise 1:
# Squares!
# Here we will be using lists and loops to create a list with the squares of the first 10 number.
# To start we define a list called squares below.
squares = [] 

# Now create a for loop (as we saw in the Python mini lesson on lists and loops) that accesses the numbers 0-9.
# Inside the loop append the square of each of these numbers to squares. Remember the square of x is x*x.



############### Bonus Exercise 2:
# Summing an array.

sum = 0
item_cost = [12, 5, 34, 12, 41, 93, 23, 44, 23] 

# Write a for loop that adds the value of each element in the list to sum.


# Print the value of sum here. It should be 287



################# Bonus Exercise 3:
# First create an array called evenNumbers.
# Now add all even numbers from 0 - 20 to evenNumbers.
# Hint: you may only need to use 11 numbers in your range!
# Code goes here:
