Python Calculator, No Answer

I am very much interested in Python and I decided to learn it. I covered many things but I am stuck when try to make a Calculator in which we just need to type the numbers and the operation type

For Example- 10 ^ 2

The thing that happens is I get no answer. And i use Command Prompt for the output.

My Code looks like this:

 # Calculator



print " "
print "  Calculator  "
print " "

num = int(raw_input(">> ")).split()

num1 = int(num[0])

op = num[1]

num2 = int(num[2])

if (op=='+'):

    print ">>>", num1 + num2
elif (op=='-'):

    print ">>>", num1 - num2
elif (op=='*'):

    print ">>>", num1 * num2
elif (op=='/'):

    print ">>>", num1 / num2
elif (op=='^'):

    print ">>>", pow(num1,num2)
elif (op=='%'):

    print ">>>", num1 % num2

I use Python 2.7.

Please Help Me For The Same.
