Python TypeError

So i've got this bot that im working but, but i came across this TypeError. All i want to do is to ensure that the content for the icon `` variable is decided on how the weather (main()) is like. I made sure thatmain()``` returns an int so if i set up an if statement, it will work properly. So as i was testing this if condition, i ran to this TypeError and got no clue what it means nor what im suppose to do. Here's the code if you're wondering: 

class Weather_Icon(main()):
    icon = '?❄'
    icons = {'sunny': '☀ ?', 'normal': '? ?', 'cold': '❄ ⛄ ?'}
    for key, val in icons.items():
        if main() <= 40:
            icon = key[3]
        elif 41 <= main() <= 75:
            icon = key[2]
        elif main >= 76:
            icon = key[3]

Any suggestions are greatly appreciated ?

Hi Ammar, I don't think I totally get what your trying to achieve, but here's what I think anyways.

class Weather_Icon():  # incorrect use of inheritance
    icon = '?❄'
    icons = {'sunny': '☀ ?', 'normal': '? ?', 'cold': '❄ ⛄ ?'}
    for key, val in icons.items():
        if main() <= 40:
            icon = val   # remove key[], replace with val
        elif 41 <= main() <= 75:
            icon = val  # remove key[], replace with val
        elif main() >= 76:  # missing ()
            icon = val  # remove key[], replace with val

I'm sure this code could be simplified much further and or written better, but I'm not entirely sure how you are using the code. It makes no sense to iterate over each item in the dictionary to set the icon.

class WeatherIcon():
    def __init__(self, value):
        icons = {'sunny': '☀ ?', 'normal': '? ?', 'cold': '❄ ⛄ ?'}
        if value > 76:
            self.icon = icons['sunny']
        elif value > 41:
            self.icon = icons['normal']
        else:
            self.icon = icons['cold']
