Question

Please answer in Python with indentation, ty.

The credit plan at TidBit Computer Store specifies a 10% down payment and an annual interest rate of 12%. Monthly payments are 5% of the listed purchase price, minus the down payment.

Write a program that takes the purchase price as input. The program should display a table, with appropriate headers, of a payment schedule for the lifetime of the loan. Each row of the table should contain the following items:

1. The month number (beginning with 1)
2. The current total balance owed
3. The interest owed for that month
4. The amount of principal owed for that month
5. The payment for that month
6. The balance remaining after payment

The amount of interest for a month is equal to balance × rate / 12.

The amount of principal for a month is equal to the monthly payment minus the interest owed.

An example of the program input and output is shown below:

Enter the puchase price: 200

Answer 1

Code:

from prettytable import PrettyTable #importing PrettyTable to print data in table

price=int(input("Enter the purchase price: ")) #asking user to enter purchase price

table = PrettyTable() #creating table objects

table.field_names = ["Month", "Starting Balance", "Interest to Pay", "Prinicipal to Pay","Payment","Ending Balance"] #adding header of tables

price=price - (price*(10/100)) #subtracting down payment from purchased price

monthly_payment = (price*(5/100)) #calculating monthly payment

month=1 #initiate month to 1

while (price>0): #Iterate loop untill price > 0

interest_to_pay = (price * (12/100))/12 #find interest to pay

principal_to_pay = monthly_payment-interest_to_pay #compute principal to pay

payment_ending_balance = price - principal_to_pay #compute payment ending balance

if price<monthly_payment: #if price less than monthly payment then print last monht and its price.
  
table.add_row([round(month,2),round(price,2),round(0.00,2),"","",""])

else: #else add the rows of every month

table.add_row([round(month,2),round(price,2),round(interest_to_pay,2),round(principal_to_pay,2),round(monthly_payment,2),round(payment_ending_balance,2)])

price=payment_ending_balance #change the price

month+=1 #increment the months

print(table)

Note: Here for better looking of table we have printed the table using PrettyTable so please install the package by usin pip install PrettyTable if it doesn't exist .In python Indentations are very important . So for perfect indentation please observe the attached code snippet.

Enter the purchase price: 200 +------- | Month | Starting Balance | Interest to Pay | Prinicipal to Pay | Payment | Ending Balance 9.0 9.0 - 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 180.0 172.8 165.53 158.18 150.77 143.27 135.71 128.06 120.34 112.55 104.67 96.72 88.69 80.57 72.38 64.1 55.74 47.3 38.77 30.16 21.46 12.68 3.8 1.8 1.73 1.66 1.58 1.51 1.43 1.36 1.28 1.2 1.13 1.05 0.97 0.89 0.81 0.72 0.64 0.56 0.47 0.39 0.3 0.21 0.13 0.0 7.2 7.27 7.34 7.42 7.49 7.57 7.64 7.72 7.8 7.87 7.95 8.03 8.11 8.19 8.28 8.36 8.44 8.53 8.61 8.7 8.79 8.87 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 9.0 172.8 165.53 158.18 150.77 143.27 135.71 128.06 120.34 112.55 104.67 96.72 88.69 80.57 72.38 64.1 55.74 47.3 38.77 30.16 21.46 12.68 3.8 - 1 1 1 1 1 1 - -
