n = [3, 5, 7]

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)

That's my code. Here's the error I get:

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

So, instead of [6, 10, 14], I get [6, 5, 7].
