while(True):
   print("\n1) Add")
   print("2) Subtract")
   print("3) Multiply")
   print("4) Divide")
   print("5) Exit")
   option=int(input("\nPlease select one of options above: "))
  
   if(option==1):
       no1=float(input("Enter the first number: "))
       no2=float(input("Enter the second number: "))
       print("Answer: %.1f"%(no1+no2))
   elif(option==2):
       no1=float(input("Enter the first number: "))
       no2=float(input("Enter the second number: "))
       print("Answer: %.1f"%(no1-no2))
   elif(option==3):
       no1=float(input("Enter the first number: "))
       no2=float(input("Enter the second number: "))
       print("Answer: %.1f"%(no1*no2))
   elif(option==4):
       no1=float(input("Enter the first number: "))
       no2=float(input("Enter the second number: "))
       print("Answer: %.1f"%(no1/no2))
   elif(option==5):
       print("Have a good day!\n")
       break
   else:
       print("Invalid option!!\n")
