Am I using proper code structure

#!/usr/bin/env python

import webbrowser

class Tors:
        def getSearch(self):
            #Gets the search that the user is looking for
            u_input = raw_input('Enter search: ')
            return u_input

        def getEngine(self):
            #Gets the engine the user would like to use to search
            engine  = raw_input('Enter engine: ')
            return engine

        def setEngine(self,eng):
            #Converts the users engine input to lowercase; Useful for error prevention. Reduces the number of possibilites for the if statements
            #Does nothing if eng is already lowercase
            eng = eng.lower()
	    #Sets eng to the site specified by the user in getEngine()
            #Resulting eng will be modified to url_eng
            #All sites have a "TEMP", symbolizing the search from getSearch()
            if eng == 'tpb' or eng == 'thepiratebay':
                url_eng = 'http://thepiratebay.se/search/TEMP/0/77/0'
            elif eng == 'kat'or eng == 'kickasstorrents':
                url_eng = 'http://kat.ph/usearch/TEMP/'

            else:
                print(eng+': is not an engine currently supported. To add an engine you will need to modify the script yourself')
            return url_eng

        def setUrl(self,torEng,u_in):
	    #Replaces the "TEMP" with the users input from getSearch()
            #This results in the last modification to the url
            full_url = torEng.replace('TEMP',u_in)
            return full_url

        def navigateUrl(self,complete_url):
            #Displays the complete_url to the screen
            #Uses the webbrowser function to navigate to the fully modified url (complete_url)
            print('Search Url: '+complete_url)
            webbrowser.open_new_tab(complete_url)

#Creates a Tors() object capable of accesing Tors() functions
#This allows the script to access functions inside the Tors() class
newSearch = Tors()
#The Users Input
userIn = newSearch.getSearch()
#The Users Engine Input
tEng = newSearch.getEngine()
#The Temporary Url (http://thepiratebay.se/search/TEMP/0/77/0) to set the engine
tempUrl = newSearch.setEngine(tEng)
#The modified url that replaces TEMP with the users input from getSearch()
modUrl = newSearch.setUrl(tempUrl,userIn)
#Navigates the the "modUrl". Which is the site followed by the serach provided
newSearch.navigateUrl(modUrl)
