builtins.TypeError: '<=' not supported between instances of 'function' and 'int'

I'm trying to finish up an assignment for class, but I'm just not getting this last piece.

I'm trying to have a function that, when given the wind speed, gives the associated warning message, but the trick is that the wind speed and warning messages and parameters are in 2 previously defined functions. Also, the teacher wanted us to call both functions all in one line.

So first I created the first 2 functions:

def storm_category(speed):
    if speed <= 129:
        return (0)
    if speed >= 130 and speed < 164:
        return (1)
    if 165 <= speed and speed < 189:
        return (2)
    if 190 <= speed and speed < 219:
        return (3)
    if 220 <= speed and speed < 259:
        return (4)
    if speed >= 260:
        return (5)

def category_warning(category):
    if category == 0:
        return "Not  a major threat"
    if category == 1:
        return "Very dangerous winds will produce some damage."
    if category == 2:
        return "Extremely dangerous winds will cause extensive damage."
    if category == 3:
        return "Devastating damage will occur."
    if category == 4:
        return "Catastropic damage will occur"
    if category == 5:
        return "Cataclysmic damage will occur."

But in the last function I'm required to use information from both:

def warning(speed):
    # Requirement: this function should be one line!

    return storm_category(category_warning)

With the above code though, every time I try to return a I get an error saying that "builtins.TypeError: '<=' not supported between instances of 'function' and 'int'". It says that the errors are on these lines:

return storm_category(category_warning)

And

if speed <= 129:
        return (0)

I'm not sure if my syntax is wrong or what. Can anyone help me?

the error is because you send the name of function and not the function call. must be:

def warning(speed):
    return category_warning(storm_category(speed))

note: in your code when the python interpreter process the operation speed <= 129, the python interpreter assumes speed is a callable function.
