        height = input.promptMessage('height','Kilo')

class BMI:
    def __init__(self,jack):
        result = jack.hieght
    def __str__(self):
        return result

    
jack = Person()
bmiCal = BMI(jack)

can someone please explain how I can get the height and weight attributes inside the Bmi object

I have had experience with java but in java I could easily pass one object inside another and use there attributes and even edit them

  • This is a simple typo. Please think about it carefully: where the code says `self.wieght = input.promptMessage('Wieght','Kilo')`, why does it say `self.wieght`, and not just `wieght`? Now, do you see how the same reasoning applies to the `BMI` class? – Karl Knechtel Jun 29 '22 at 03:52
  • As an aside: the words are spelled `height` and `weight`, respectively. – Karl Knechtel Jun 29 '22 at 03:52
