🔒 beginner here, need help with functions

Hey @still matrix!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

• Explain what you expect to happen and what actually happens.

def calculate_bmi(height, weight):
    
    BMI = weight / height**2


    if BMI < 18.5:
        return 'underweight'
    elif 18.5 <= BMI <= 24.9:
        return 'normal'
    elif 25 <= BMI <= 29.9:
        return 'overweight'
    else:
        return 'obese'

why is it that when i run the code, it just says program finished

you never called the function, in other words you made the function but never gave it any inputs to work with - and you also never printed any text to the screen

Print and return

Here's a handy animation demonstrating how print and return differ in behavior.

def calculate_bmi(height, weight):
    
    BMI = weight / height**2

    if BMI < 18.5:
        return 'underweight'
    elif 18.5 <= BMI <= 24.9:
        return 'normal'
    elif 25 <= BMI <= 29.9:
        return 'overweight'
    else:
        return 'obese'
        
h = float(input('Enter height here (in meters): '))
w = float(input('Enter weight here (in kilograms): '))
print(calculate_bmi(h, w))

like this?
