3 Arguments - Calculating BMI - Phython : So basically Im trying to create a program which should do the following in phython: 



A Program that contains a function called calculate_bmi which when it is called, has three arguments - the first argument is an integer variable containing the height in feet, the second argument is an integer variable containing the height in inches, the third argument is the person's weight in pounds. The main program asks the user to enter feet, then inches, then pounds. These variables are then sent to the function. The function calculates and prints the BMI value.

This is my code below im trying to do but no luck, i cannot seem to convert the height to feet as well. any help would really be appreciated.
    

    def calculate_bmi():
    
       height_feet = int(input("Please enter height in feet"))
       height_inches = int(input("Please enter height in inches"))
       weight_pounds = int(input("Please enter weight in pounds"))
        
       calculate_bmi(height_feet,height_inches,weight_pounds)
       
       bmi = (weight_pounds / height_inches) * 703
       
       print (bmi)
