a. Show the expression that gets the value of the stock dictionary at the key “orange”

stock = {"banana": 6, "apple": 0, "orange": 32, "pear": 15}
prices = {"banana": 4, "apple": 2, "orange": 1.5, "pear": 3}

stock[“cherry”] = 19 price[“cherry”] = 3.5

b. Iterate over stock dictionary and print each key and value

for fruit in stock: print(fruit, stock[fruit])

c. Sum the total items in the grocery list

groceries = [“apple”, “banana”, “pear”] grocery_total = 0 for item in groceries: print(prices[item]) grocery_total += prices[item] print(‘grocery total:’, grocery_total)

d. Print out the total value in stock of all the itmes

totals = [] for fruit in stock: print(prices[fruit] * stock[fruit]) totals.append(prices[fruit] * stock[fruit]) print(‘total value in stock:’, sum(totals))

All together:

stock = {“banana”: 6, “apple”: 0, “orange”: 32, “pear”: 15} prices = {“banana”: 4, “apple”: 2, “orange”: 1.5, “pear”: 3} stock[“cherry”] = 19 prices[“cherry”] = 3.5 for fruit in stock: print(fruit, stock[fruit]) groceries = [“apple”, “banana”, “pear”] grocery_total = 0 for item in groceries: print(prices[item]) grocery_total += prices[item] print(‘grocery total:’, grocery_total) totals = [] for fruit in stock: print(prices[fruit] * stock[fruit]) totals.append(prices[fruit] * stock[fruit]) print(‘total value in stock:’, sum(totals)) ```

OUTPUT: banana 6 apple 0 orange 32 pear 15 cherry 19 2 4 3 grocery total: 9 24 0 48.0 45 66.5 total value in stock: 183.5
