Hello you guys, I have a problem need your help. I created a small project with Python 3.8.2 to help calculate BMI points for humans. You can see like this:
weight = input('How much do you weigh?:') height = float(input('How tall are you?:')) bmi = weight / (height *2) print('BMI: ', bmi)
But when I'm inputting weight = 78 and tall = 1.75 I get an error throw TypeError: unsupported operand type(s) for /: 'str' and 'float'
How much do you weigh?:78 How tall are you?:1.75 Traceback (most recent call last): File "main.py", line 3, in <module> bmi = weight / (height *2) TypeError: unsupported operand type(s) for /: 'str' and 'float'
How can I resolve it?
Thanks for any suggestions.

You need to convert the input string to int or float number by using
int()
orfloat()
methods before you execute multiplication:weight = float(input('How much do you weigh?:')) height = float(input('How tall are you?:')) bmi = weight / (height * 2) print('BMI: ', bmi)
And below is the output:
How much do you weigh?:89 How tall are you?:1.73 BMI: 25.722543352601157
hope it helpful for you.
