## I'm stuck on this one and I'm not sure why.

n = [3, 5, 7]

def double_list(x):

for i in range(0, len(x)):

x[i] = x[i] * 2

return x

print double_list(n)

## double_list(n)

its saying this:

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

Can anyone identify what I've done wrong here? Thank you
