Create BMI Calculator using Python
In the following tutorial, we will understand how to create a Body Mass Index (BMI) Calculator with the help of the Python programming language. But we get started creating one; let us briefly discuss what Body Mass Index (BMI) is.
Understanding the Body Mass Index (BMI)
BMI, short for Body Mass Index, is a measure of relative weight based on the mass and height of an individual. We generally use the Body Mass Index in order to categorize people on the basis of their height and weight. These categories are underweight, healthy, overweight, and even obesity. Moreover, it is also adopted by various countries in order to promote healthy eating.

We can consider Body Mass Index (BMI) as a substitute for direct measurements of body fat. Besides, BMI is a low-cost and easy-to-perform method of screening for weight classes that may cause health-related problems.

Understanding the working of BMI Calculator
A BMI Calculator accepts the weight and height of an individual and calculates the Body Mass Index (BMI) of that person.
For Example, if the height and weight of a person are 155 cm and 57 kg. The BMI of that person will be 23.73 (approx.), which signifies that the person is healthy.
Body Mass Index (BMI) is a measure of body fat on the basis of height and weight, respectively.
