Thank you.

def total(initial=5, *numbers, extra_number):
count = initial
for number in numbers:
count += number
count += extra_number
print(count)
total(10, 1, 2, 3, extra_number=50)

Answer 1

Maybe because in the first case extra_number is added 1 time (outside the loop), and in the second case 3 times (in the loop)?
