Question

A bank charges $10 per month plus the following check fees for a commercial checking account: $.10 each for less than 20 checks $.08 each for 20 - 39 checks $.06 each for 40 - 59 checks $.04 each for 60 or more checks Write a program that prompts the user for the number of checks written each month. Then compute and display the bank’s total service fees for the month. Make sure the output displays with a $ and 2 decimal places. Also, use input validation to handle possible errors in the user input. This program MUST use a decision structure. im using python please help.

Answer 1

total_fees = 0  # variable to store total fees
month = 1  # month counter

# using while to calculate the fees for each month and calculate total fees for each month
while(month <= 12):

   fixed_charges = 10 # initializing fixed charges 
   monthly_fee = fixed_charges    # variable to store monthly fee

   # using a try-except block to validate inputs
   while True:

      # prompt to ask user for numeber of checks written each month
      checks = input('Enter the number of checks wirtten in month {}: '.format(month))

      try:
         checks = int(checks)

      except ValueError:
         print('Valid number, please')
         continue

      if 0 <= checks:
         break
      else:
         print('Please enter a valid number')

   # using if-elif structure to calculate the additional charges and hence total monthly fee
   if checks < 20:
      check_fees = 0.1
      monthly_fee += check_fees * checks

   elif checks >= 20 and checks < 40:
      check_fees = 0.08
      monthly_fee += check_fees * checks
      
   elif checks >= 40 and checks < 60:
      check_fees = 0.06
      monthly_fee += check_fees * checks

   elif checks >= 60:
      check_fees = 0.04
      monthly_fee += check_fees * checks
   
   # increment the month counter
   month += 1

   # add monthly charges to total fees
   total_fees += monthly_fee
   print(monthly_fee)

# display the result
print('Total Bank Charges are: ${}'.format(round(total_fees, 2)))
