Practice Makes Perfect : product

The emulator returns the following error:

Oops, try again. Your function crashed on [1, 2] as input because your function throws a "list index out of range" error.

When I run this on my laptop, it works as expected.

```
def product(numbers):
a = numbers[0]
b = numbers[1]
c = numbers[2]
total = a * b * c
return total
first_number = int(raw_input('Enter a number: '))
second_number = int(raw_input('Enter a second number: '))
third_number = int(raw_input('Enter a third number: '))
numbers = list()
for x in first_number, second_number, third_number:
numbers.append(x)
print product(numbers)
```
