Task 1 - Colors of the Rainbow
# A. Make a list called colors that stores 7 strings, each a color of the rainbow
colors = ['red','orange','yellow','green','blue','indigo' , 'violet']
Run to view results
# B. Then, print the following string, using list indices to access the specific colors:
# "The colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet"
# String concatenation might get a bit complex to read: try using an f-string for string interpolation!

Task 3 - The Realtors

# B. Our web designers want a statement reading: "This 3 bedroom house costs 250000"
# Print that statement by accessing the values from the dictionary: do NOT "hard-code" the string!

# G. Print the entire listing. You should see a dictionary similar to the following:
