Question No. 1

For an e-Shop, there is a Customer whose data is stored in a file ‘Customers.txt’, where ID, Name, Phone, Address, Email, and AmountBalance. When the customer buys a product and pays from his AmountBalance, the system checks his balance and deducts if enough amount is there. Otherwise, the customer receives a message “You don’t have sufficient Balance in your wallet”.

1. Write python code to create a ‘Customers.txt’ file with at least one customer’s record.


2. Write a function
   pay(), that takes
   
   amount
   
   as an input, reads the file and gets AmountBalance, print “Successful Transaction” when payment can be made or a message “You don’t have sufficient Balance in your wallet”.


3. Write a function
   checkBalance(), that reads the file and gets AmountBalance, prints “Amaount Balance”


4. Write a function
   recharge(), that takes “Enter Amount you want to recharge”, reads the file and gets AmountBalance, adds the new amount in AmountBalance, update the file, and prints “Success”
