please help me with python functional programming

I have no idea how to solve it, but it seems really close to the right answer...

temperatures = [
    37,
    0,
    25,
    100,
    13.2,
    29.9,
    18.6,
    32.8
]


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

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

Hey,

you will need to repeat the variable temperature in the and-statement so like this:

good_temps=[(...] and temperature <=32.6]

Hello Pala,

You don't need the map-function in your solution. You can just use the function c_to_f in your list comprehension. Remember that list comprehensions are defined with angle brackets. Part of the solution:

good_temps=[c_to_f(temperature) for temperature in (...)]

Hope this helps.

thank you! but I still stuck at " if the Celsius temperature is between 9 and 32.6."

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

python can't underdstand what I mean
