Question

In Python-- Write a class called Account that has two instance variables, namely, accountNumber and balance. Provide the following:

a) An init() method that takes two parameters, accountNumber and initialBalance, and does the following:

i) Sets accountNumber using the accountNumber.

ii) Sets balance using the parameter, initialBalance.

b) A withdraw() method that takes an amount as its parameter and performs the withdraw transaction. Your method should ensure that the balance does not drop below 0.

c) A deposit() method that takes an amount as its parameter and performs the deposit transaction.

d) A __str__() method that returns an appropriate string (i.e., displays account number and balance) that represents the account object. Note: The keyword self has to be used correctly.

Explanation / Answer

Python Code:

class Account:

   accountNumber = 0;
   balance = 0.0;
  
   def __init__(self,accountNumber, balance):
       self.accountNumber = accountNumber;
       self.balance = balance;
      
   def withdraw(self,amount):
       if self.balance - amount < 0:
           print("Insufficient Funds... Transaction can't be processed");
       else:
           self.balance = self.balance - amount;
          
   def deposit(self,amount):
       self.balance = self.balance + amount;

   def __str__(self):
       return " Account Number: " + str(self.accountNumber) + " Balance: " + str(self.balance);          

      
acc = Account(123456, 6000);

acc.withdraw(2000);
acc.deposit(4000);
print(acc);
