# Step 1: make the hours list
hours = [3, 5, 2, 4]

# Step 2: start total at 0
total = 0

# Step 3: FOR EACH -> for ... in ...: add each h to total
for h in hours:
    total += h

# Step 4: LENGTH(hours) -> len(hours): compute the average
average = total / len(hours)

# Step 5: print total, then average
print(total)
print(average)
