Question

Develop a class BankAccount where each created object will have a single instance variable called balance of type float. It support the following methods/ functions: Constructor: Takes a float bal as parameter and initializes the balance to this bal. withdraw: Takes no parameters, asks the user to input an amount and deducts this amount from the balance. deposit: Takes no parameters, asks the user to input an amount, and adds this amount to the balance. Get balance: Takes no parameters, and returns the balance of the account. Outside of the doss, create 5 bank accounts and test your class. For e.g., one bank account testing could be: acc1 a BankAccount (700) acc1 .withdraw acc .deposit print ("The account balance is + str(accl.getbalance)) could produce the following (assuming I input 10 and 20 as withdrawal and deposit respectively) Please enter amount to withdraw: 10 Please enter amount to deposit: 20 The account balance Is 710
