Not wrong, but you have not used list comprehension. Consider a list called 'a' with even and odd numbers. Now suppose you want to create a list 'b' that contains only the even numbers of list 'a'.
One way to do this in the usual way with a loop:
b = []
for n in a:
if n % 2 == 0:
b.append(n)
Using list comprehension this would look like this single line:
b = [n for n in a if n % 2 == 0]
The challenge in this problem is creating nested list comprehesions, which can be tricky. See PEP 202.
