I'm trying to make a bmi calculator in python and I don't know what I'm doing wrong

Question

This is my code

weight = float(input("Please Enter Your Weight In KIlograms: "))
height = float(input("Please Enter Your Height In Meters: "))

result = weight / height ** height
print("Your BMI is " + result)

And this is the error:

OverflowError: (34, 'Result too large')

I'm really not to familiar with the technical terms yet, so you might have to be a little more specific in your explanation.

If you add parenthesis like `result = (weight / height) ** height` — Nathan Wride, Oct 29 '20 at 08:31

You mean `height**2` (height squared), not `height**height` (height to the power of height) — khelwood, Oct 29 '20 at 08:32
@NathanWride I think it is more likely they meant `weight / (height * height)` (or simply `weight / height**2`) — Tomerikoo, Oct 29 '20 at 08:34
@MuhammadJunaidHaris while it is the same error, it is not the same cause and the duplicated question doesn't answer this one... — Tomerikoo, Oct 29 '20 at 08:54

Try something like this

height = float(input("Input your height in meters: "))
weight = float(input("Input your weight in kilogram: "))
print("Your body mass index is: ", round(weight / (height * height), 2))

your code needs some changes. Your final print statement tries concatenate a string and a float ie the string being "Your BMI is " the float being result. So you have to make them both the same type as below. ("Your BMI is " + str(result)). And also the BMI equation is Weight/Height^2 rather than Weight/ Height^Height. So change the calculation part to result = weight / height ** 2.

weight = float(input("Please Enter Your Weight In Kilograms: ")) 
height = float(input("Please Enter Your Height In Meters: "))

result = weight / height ** 2 
print("Your BMI is " + str(result))
