If statement isnt working?(Python)

My if statement won't work, i am a beginner and yes i've looked at least 5 examples if you're wondering and i still can't get it right. I feel like it's correct yet it still won't do what i want it to do.

There is more code if you're wondering but it shouldn't do anything to this

  Start = 0
    Start = input("-->: ")
    if Start == 3:
        print ("successful")
