Practical A4 :

 Write a Python program that computes the net amount of a bank account based a transaction log from console input. The transaction log format is shown as following: D 100 W 200 (Withdrawal is not allowed if balance is going negative. Write functions for withdraw and deposit) D means deposit while W means withdrawal. Suppose the following input is supplied to the program: D 300, D 300 , W 200, D 100 Then, the output should be: 500

The code for above problem is as follows :

 print("""       HELLO  
    WELCOME TO OUR BANK""")  
      
     
 balance=0  
   
 def deposit():  
     global balance  
       
       
     
     while True:  
         
       amount=float(input("Enter amount to be Deposited: "))   
   
       balance += amount   
       print("\n Amount Deposited:",amount)   
       
       res=input ("Do you want to Deposite more money? y or n ")  
       if res=='n':  
         print("\n Your Total Balance is ",balance)  
         break  
   
    
   
 def withdraw():  
     global balance  
     
     while True:  
   
       amount = float(input("Enter amount to be Withdrawn: "))   
   
       if balance>=amount:   
   
         balance-=amount   
         print("\n You Withdrew:", amount)   
         print("\n Your Total Balance is ",balance)  
   
       else:   
   
         print("\n Insufficient balance ")   
         
       res=input ("Do you want to withdraw more money ? y or n ")  
       if res=='n':  
         print("\n Your Total Balance is ",balance)  
         break    
 while True:  
     
   res=input ("""What do you want to do?  
           PRESS 'd' to deposit money  
           PRESS 'w' to withdraw money  
           PRESS 'e' to exit\n""")  
   if res=='d':  
     deposit()  
   elif res=='w':  
     withdraw()  
   elif res=='e':  
     break  
   else:  
     print("""SORRY!!!  
      You have given wrong input""")
