BMI Calculator by python

What is the BMI?

Body Mass Index (BMI) is a person’s weight in kilograms divided by the square of height in meters. A high BMI can indicate high body fatness. BMI screens for weight categories that may lead to health problems, but it does not diagnose the body fatness or health of an individual.

so in the program I start by taking the height and the weight from user :

w=float(input("Please Enter your Weight"))
h=float(input("Please Enter your Height"))

then I calculated the BMI :

BMI=w/(h/100)**2

---

then I converted the result from float to string to concatenate it print sentence:

bmi=
