Can I get help with this program please.

Instructions

1. Make sure that the file HouseholdSize.py is selected and open.
2. Write the bubble sort.
3. Calculate the total of the household size.
4. Output the mean and median household size in Marengo.
5. Execute the program by clicking the Run button and the bottom of the screen.
6. Enter the following input, and ensure the output is correct. Household sizes: 4, 1, 2, 4, 3, 3, 2, 2, 2, 4, 5, 6 followed by 999 to exit the program.

This is the code I have

# Initialize variables.

householdSizes = [] # Array used to store household sizes.

numSizes = 0

total = 0.0

mean = 0.0

median = 0.0

# Input household size

householdSizeString = input("Enter household size or 999 to quit: ")

householdSize = int(householdSizeString)

# This is the work done in the fillArray() function

while (householdSize != 999):

# Place value in array.

householdSizes.append(householdSize)

# Calculate total of household sizes

numSizes += 1 # We have one more house

householdSizeString = input("Enter household size or 999 to quit: ")

householdSize = int(householdSizeString)

# Find the mean

def findMean(householdSizes):

sum_val=0

#summing the values in householdSizes

for i in householdSizes:

sum_val+=i

#dividing by length of householdSizes to get the mean value

return sum_val/len(householdSizes)

# This is the work done in the sortArray() function

def sortArray(householdSizes):

#using bubble sort algorithm to sort householdSizes in ascending order

for i in range(len(householdSizes)):

for j in range(len(householdSizes)-1):

#comparing elements at indices j and j+1

if householdSizes[j]>householdSizes[j+1]:

#swapping elements at indices j and j+1

householdSizes[j],householdSizes[j+1]=householdSizes[j+1],householdSizes[j]

# This is the work done in the displayArray() function

def displayArray(householdSizes):

#printing all elements in householdSizes separated by comma and space

for i in range(len(householdSizes)):

print(householdSizes[i],end='')

#if this is not last item printing ', '

if i!=len(householdSizes)-1:

print(', ',end='')

print()

# Find the median

if len(householdSizes)%2!=0:

median=householdSizes[len(householdSizes)//2]

else:

median=(householdSizes[len(householdSizes)//2] + householdSizes[(len(householdSizes)//2) -1])/2

#displaying median

print('Median of household sizes:',median)
