# A. Make a list called colors that stores 7 strings, each a color of the rainbow colors = ['red','orange','yellow','green','blue','indigo' , 'violet']

# 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! range_1 = [0,1,2,3,4,5,6] for i in range_1: print(f" colors: {colors[i]}")

# C. Change two of the colors to more descriptive names, such as "Lightning Yellow" or "Deep Sea Blue" colors[2] = "lightning yellow" colors[4] = "Deep Sea Blue" print(f" {colors[2]} & {colors[4]}")

# D. Print the two new color names using list indices to access them print(f" {colors[2]} & {colors[4]}")

# E. Print the colors variable to see the difference between printing a specific item and printing the list itself print(f" {colors}")

# You will have to research some new methods to use for these challenges # You can use print statements to investigate whether your changes have succeeded as expected candidates = ["Alice", "Boris", "Carmen"]

# C. One of our generous donors has a nephew, Aaron, who should be added to the very front of the list candidates.insert(0,"Aaron") print(candidates)

# D. Boris's parents are concerned. Use the .index() method to print a message explaining Boris's place in the list print(f" Mr and Mrs Boris your son is currently {candidates.index('Boris') +1 } on the list")

# E. Carmen is upset by the priority given to relatives of donors, and has withdrawn their application. # Use the .remove() method to remove them from the list. candidates.remove('Carmen') print(candidates)

# F. Use a method to remove the very first student in the list, as they have now been accepted! candidates.pop(0) print(candidates)

# G. DeSean has submitted an impressive personal statement. Place them at index 1 by using .insert() candidates.insert(1,"G. DeSean") print(candidates)

# Use the house dictionary for the following challenges house = { "address": "123 Fake Street", "price": 750000, "bedrooms": 3, "lat/long": (38.5387, 122.6955), "available": True}

# A. Buyers can't find the house without a zip code! Add a zip_code property equal to "95404" house["zip_code"] = 95404 print(house)

# 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! print(f" This {house['bedrooms']} bedroom house costs ${house['price']} ")

# C. We're getting a lot of interest in the house! Let's increase the price by 10% house['price'] = house['price'] * 1.1 house['price']

# D. Buyers are surprised at how small the house is. Let's add a square_feet property equal to 750 house['square_ft'] = 750

# E. We want to show off the value per foot. Print a message explaining the price per square foot. print(F" The price per square_ft is ${house['price']/house['square_ft']}")

# F. After 2 long hours on the market, the house has finally sold! Change availability to False. Add a status property equal to "sold" house['available'] = False house['status'] = 'sold'

# G. Print the entire listing. You should see a dictionary similar to the following: # {address: "123 Fake Street", price: 825000, bedrooms: 3, zip_code: "95404" square_feet: 750, status: "sold"} print(house)
