Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

I have an assignment to make a bunch of sensors work for tomorrow (In like 8 hours). Pls I would really appreciate it if someone could check my functions and tell me if they would work properly and tell me the mistakes.

    class MQ7(object):

        # The load resistance on the board
        RLOAD = 10.0
        # Parametros para calcular CO
        PARA = 116.6020682
        PARB = 2.769034857
        
        def __init__(self, pin):
            self.pin = pin

        def get_resistance(self):
            adc = ADC(Pin(self.pin))
            value = adc.read_u16()
            if value == 0:
                return -1
            return (1023./value - 1.) * self.RLOAD

        def get_ppm(self):
            #10=R0 at 1000ppm, placeholder for now
            return  self.PARA * (self.get_resistance()/ 10)**-self.PARB

    mq7 = MQ7(2) #GPIO pin

    while True:
        ppm = mq7.get_ppm()
