BMI calculator

[samic]

Hello
I have just started learning Python and I have so many problem in solving my exercise. I know the answer I have written is not correct. Can any body help me?
the question is:
The body mass index (BMI) is calculated as a person’s weight (in pounds) times 720, divided by the square of the person’s height (in inches). A BMI in the range 19-25, inclusive, is considered healthy. Write a program that calculates a person’s BMI and prints a range telling whether they are above, within, or below the healthy range. (20 pts)

I have written:

def bmi_calculate():
 
    weight, height = input("Enter weight and height seperated by a comma:")
    bmi_calculate = [(weight * 720) / (height * height)]
 
    for bmi_calculate in range (19,25):
        where = 'healthy'
        if bmi_calculate < 19:
            where = 'below'
        elif bmi_calculate > 25:
            where = 'high'
 
 
print "your bodey mask index is:" , bmi_calculate

I cant run this.
can any one edit it for me?? Thanks

def bmi_calculate(a,b): #a = weight and b = height
 
    a, b = input("Enter weight and height seperated by a comma:")
    bmi = (a * 720) / (b * b)
    print "the BMI is:" , bmi
 
    for n in range (19,25):
        return 'healthy'
        if n < 19:
            return 'below'
        elif n > 25:
            return 'high'
print bmi_calculater(a,b)

@samic
Do not use bmi_calculate as an identifier, because that is the name of the function.

Do not enclose the calculation in brackets. That creates a list. Do this instead:

bmi = (weight * 720.0) / height**2

Why are you using a for loop? You need to determine where the calculation result is with respect to the range 19 through 25. An if/elif block would be appropriate. The first line would be:

if 19 <= bmi <= 25:

You must return a value. Use the return statement to return bmi.

You must call the function by following the function name with parentheses. Look at the difference:

>>> print "your bodey mask index is:" , bmi_calculate
your bodey mask index is: <function bmi_calculate at 0x00C2E1F0>
>>> print "your bodey mask index is:" , bmi_calculate()
your bodey mask index is: healthy

You misspelled body mass!
