Prerequisite: Object Oriented Programming in Python
Let’s write a simple Python program using OOP concept to perform some simple bank operations like deposit and withdrawal of money.
First of all, define class Bankacccount. This step is followed by defining a function using __init__. It is run as soon as an object of a class is instantiated. This __init__ method is useful to do any initialization you want to do with object, then we have the default argument self.
Python3
class Bankaccount:
def __init__( self ):
|
This step is followed by declaring that balance is 0 using self argument then we simply print a statement welcoming to Machine. In function deposit and withdraw , amount is taken as input(in float) and is then added/subtracted to the balance. Thus resultant balance is printed in next line.
Python3
def deposit( self ):
amount = float ( input ( "Enter amount to be deposited: " ))
self .balance + = amount
print ( "\n Amount Deposited:" , amount)
|
Use an if condition to check whether there is a sufficient
amount of money available in the account to process a fund withdrawal.
Python3
def withdraw( self ):
amount = float ( input ( "Enter amount to be withdrawn: " ))
if self .balance > = amount:
self .balance - = amount
print ( "\n You Withdrew:" , amount)
else :
print ( "\n Insufficient balance " )
|
Next, we use a display function to display the remaining balance in the account. Then we create a object and call it to get the program executed.
Python3
def display( self ):
print ( "\n Net Available Balance =" , self .balance)
|
Below is the implementation:
Python3
class Bank_Account:
def __init__( self ):
self .balance = 0
print ( "Hello!!! Welcome to the Deposit & Withdrawal Machine" )
def deposit( self ):
amount = float ( input ( "Enter amount to be Deposited: " ))
self .balance + = amount
print ( "\n Amount Deposited:" ,amount)
def withdraw( self ):
amount = float ( input ( "Enter amount to be Withdrawn: " ))
if self .balance> = amount:
self .balance - = amount
print ( "\n You Withdrew:" , amount)
else :
print ( "\n Insufficient balance " )
def display( self ):
print ( "\n Net Available Balance=" , self .balance)
s = Bank_Account()
s.deposit()
s.withdraw()
s.display()
|
Output:
Hello !!! Welcome to Deposit&Withdrawal Machine
Enter amount to be deposited:
Amount Deposited: 1000.0
Enter amount to be withdrawn:
You Withdrew: 500.0
Net Available Balance = 500.0
