I'm getting an invalid syntax

travel_expenses = [
    [5.00, 2.75, 22.00, 0.00, 0.00],
    [24.75, 5.50, 15.00, 22.00, 8.00],
    [2.75, 5.50, 0.00, 29.00, 5.00],
]

print("Travel Expenses:")
week_number = 1
for week in travel_expenses:
    print("* week #{}: ${}".format(week_number, sum(week))
    week_number += 1

This is the error week_number += 1 SyntaxError: invalid syntax

It looks like the parentheses are unbalanced on the "print" statement on the 2nd to last line.
One more closing parenthesis is needed at the end.
