is this what you want,

def testHook():
    """
    """
    choice = raw_input("Would you like to continue (Y or N): ")
    try:
        if(str(choice).lower() != 'y'):
            print("You chose not to go ahead. Ok!!\nAborting Now...")
            raise Exception("User initiated Abort...")
    except Exception, e:
        print e.message
