Question

Write a Python program to determine the body-mass index of a collection of six individuals. Your program should include a list of six names. Using a for loop, it should successfully prompt the user for the height in inches and weight in pounds of each individual. Each prompt should include the name of the individual whose height and weight are to be input. It should call a function that accepts the height and weight as parameters and returns the body mass index for that individual using the formula weight × 703 / height². That body mass index should then be appended to an array. Using a second loop it should traverse the array of body mass indices and call another function that accepts the body mass index as a parameter and returns whether the individual is underweight, normal weight, or overweight. The number of individuals in each category should be counted and the number in each of those categories should be displayed. You should decide on the names of the six individuals and the thresholds used for categorization.

CODE:

# function that accepts the height and weight as parameters and

# returns the body mass index

def calculate_bmi(height, weight):

    bmi = weight * (703/(height ** 2))

    return bmi

# function that accepts the body mass index as a parameter and

# returns whether the individual is underweight, normal weight, or overweight

def bmi_category(bmi):

    #conditions

    if ( bmi < 16):

        return "underweight"

    elif ( bmi >= 16 and bmi <= 25):

        return "normalweight"

    elif (bmi > 25):

       return "overweight"

   

#program starts here

#creating list of six names

name_list = ["Adam", "Eden", "Tom", "George", "Nina", "Cody"]

bmi_list = [] #declare an empty list for bmi

for name in name_list: #loop through each name in name_list

    # getting height and weight for each person

    height = float(input(name + ", Enter your height in inches: "))

    weight = float(input(name + ", Enter your weight in pounds: "))

    bmi = calculate_bmi(height, weight) #calculating the bmi for particular person

    bmi_list.append(bmi) #appending the bmi to bmi_list

#initialize number of underweight, normalweight and overweight persons as 0

num_under = 0

num_normal = 0

num_over = 0

for bmi in bmi_list: #loop through each bmi in bmi_list

    category = bmi_category(bmi) #finding the category

    if category == "underweight": #increment num_under by 1 if category is underweight

        num_under = num_under + 1

    elif category == "normalweight": #increment num_normal by 1 if category is normalweight

        num_normal = num_normal + 1

    elif category == "overweight": #increment num_over by 1 if category is overweight

        num_over = num_over + 1

#displaying the number of individuals in each category

print("\nNumber of underweight persons: ", num_under)

print("Number of normalweight persons: ", num_normal)

print("Number of overweight persons: ", num_over)

OUTPUT:
