Question

Write a python program that executes the following conditions:
A store owner keeps a record of daily cash transactions in a text file. Each line
contains three items: The invoice number, the cash amount, and the letter P if the
amount was paid or R if it was received. Items are separated by spaces. Write a program
that prompts the store owner for the amount of cash at the beginning and end
of the day, and the name of the file. Your program should check whether the actual
amount of cash at the end of the day equals the expected value.

Example,
Enter the beginning cash balance: 35
Enter the ending cash balance: 70
Enter the file name: balance.txt
The closing balance does not match. It Should be 60.00

Answer 1

def main():
    initial = float(input('Enter the beginning cash balance: '))
    final = float(input('Enter the ending cash balance: '))
    filename = input('Enter the file name: ')
    total = 0
    with open(filename, 'r') as f:
        for line in f:
            words = line.strip().split()
            total += float(words[1])
    total += initial
    if total == final:
        print('The closing balance does match.')
    else:
        print('The closing balance does not match. It Should be %.2f' % total)

main()

Def main(): initial = float(input('Enter the beginning cash balance: ')) final = float(input('Enter the ending cash balance: ')) filename = input('Enter the file name: ') total = 0 with open(filename, 'r') as f: for line in f: words = line.strip().split() total += float(words[1]) total += initial if total == final: print('The closing balance does match.') else: print('The closing balance does not match. It Should be %.2f' % total) main() Enter the beginning cash balance: 35 Enter the ending cash balance: 70 Entre the file name: balance.txt The closing balance does not match. It should be 60.00 Process finished with exit code 0
