what is wrong...

I keep getting the error message:

Oops, try again. double_list([0, 1]) returned [0, 1] instead of [0, 2]

Also the editor shows [6, 5, 7] even though it is supposed to show each element multiplied by two:

[6, 10, 14]

I know I am only multiplying n[0] but what do I need to change to get each element * 2

Here is my code:

```
def double_list(x):
for i in range(0, len(x)):
x[i] = x[i] * 2
return x
# Don't forget to return your new list!
print double_list(n)
```
