functional python map and filter comprehension quiz solution??

according to me, my codes are correct. but i give an "use list comprehension" error. i didnt understand?


temperatures = [

def c_to_f(temp):
    """Returns Celsius temperature as Fahrenheit"""
    return temp * (9/5) + 32

good_temps = map(c_to_f,[tempval for tempval in temperatures if tempval > 9 and tempval < 32.6])

There is another way of doing the same thing that map is doing and it's called list comprehension. Kenneth explained it a bit in that course but for more detailed explanation you should watch this http://teamtreehouse.com/library/python-comprehensions.

It should look like this :

good_temps = [c_to_f(temp) for temp in temperatures if temp > 9 and temp < 32.6]

Yeah, you need to use only a list comprehension, no calls to map() at all, in this challenge.
