Calculating BMI through Python: Take 2

Question

Sorry about my previous question. The question I have to answer is this: Body Mass Index (BMI) is a good indicator of body fatness for most people. The formula for BMI is weight/ height2 where weight is in kilograms and height is in meters. Write a program that prompts for weight in pounds and height in inches, converts the values to metric, and then calculates and displays the BMI value. What I have so far is this: ``` """ BMI Calculator 1. Obtain weight in pounds and height in inches 2. Convert weight to kilograms and height to meters 3. Calculate BMI with the formula weight/height^2 """ #prompt user for input from keyboard weight= input ("How much do you weigh (in pounds)?") #this get's the person's weight in pounds weight_in_kg= weight/2.2 #this converts weight to kilograms height= input ("What is your height (in inches)?") #this gets the person's height in inches height_in_meter=height*2.54 #this converts height to meters bmi=weight_in_kg/(height_in_meters*2) #this calculates BMI…

Accepted Answer

For Python 3.x (as specified):

The problem is that keyboard input from `input()` is of type `str` (string), which is not a numeric type (even if the user types in numbers). However, this is easily fixed by changing the input lines like so:

```
weight = float(input("How much do you weigh (in pounds)?"))
```

and

```
height = float(input("What is your height (in inches)?"))
```

thus converting the string output of `input()` into the numeric `float` type.
