PRACTICAL: - 3 Aim: - Write a Python program which accept input from the user and perform following operations: i) Addition ii) Subtraction iii) Multiplication iv) Division

num1=input("Enter 1st number : ") num2=input("Enter 2nd number : ") ch=input("Enter operator(+,-,*,/) : ")

if ch=='+': ans=int(num1)+int(num2) print(num1,"+",num2,"= ",ans) elif ch=='-': ans=int(num1)-int(num2) print(num1,"-",num2,"= ",ans) elif ch=='*': ans=int(num1)*int(num2) print(num1,"*",num2,"= ",ans) elif ch=="/": ans=int(num1)/int(num2) print(num1,"/",num2,"= ",ans) else : print("Please enter above mentioned operations..")
