Create a function called double_list that takes a single argument x (which will be a list) and multiplies each element by 2 and returns that list. Use the existing code as a scaffold.
I did this:
n = [3, 5, 7]
for i in x(0, len(x)):
x[i] = x[i] * 2
And the freaking thing says that “list” object is not callable
