Exercise 1

Simplify the following code using the function sum():

counts = [356, 412, 127, 8, 32]

total = 0
for number in data:
    total = total + number
print(total)

Exercise 2

Simplify the following code using the function range():

i = 0
while i < 10:
    print(i * '*')
    i += 1

Exercise 3

Simplify the following code using the function zip():

names = ['Lilly', 'Lily', 'Leila', 'Lilja', 'Lillie']
counts = [356, 412, 127, 8, 32]

table = []
i = 0
while i < len(names):
    row = (names[i], counts[i])
    table.append(row)
    i += 1
print(table)

Exercise 4

Simplify the following code using the function enumerate():

names = ['Lilly', 'Lily', 'Leila', 'Lilja', 'Lillie']

i = 0
for name in names:
    print(i, name)
    i += 1
