This is what I believe the error is referring to. This is wrong because it wants you to print the variable original which you defined here:
original = raw_input("shubham")
In the console, it will let you enter a word, and whatever word you enter will be original.
I'm not sure if you know how the raw_input() function really works? Whatever string that you pass into the raw_input() function will be printed as a sort of instruction, but it doesn't matter what string you pass it. I used something like "Please enter a word"
