program that reads two numbers and an arithmetic operator and displays the computed result.

-
num1=float(input("Enter first number:")) num2=float(input("Enter second number:")) op=input("Enter operator[ + - * / % ]:") result=0 If op == '+':         result=num1+num2 else op =='-':        result=num1-num2 else op =='*':        result=num1*num2 else op =='/':        result=num1/num2 else op =='%':        result=num1%num2 else:       print ("Invalid operator!!") print(num1,op,num2,'=',result) Output Enter first number:5 Enter second number:2 Enter operator[ + - * / % ]: * 5.0*2.0=10.0
