Repeat a input line until valid input is given

Question

I'm making one of those really old text games.

I give the player two options.

I let them choose like this:

Run = input("Do you:
                     1. Run
                     2. Stay.")

Then, an if statement saying if they choose option:

Then we get to my problem.

If they enter something other than choice 1 and 2, then I want it to repeat the question until they finally choose either option 1 or 2.

So? Have you tried anything? Done any research? See e.g. http://stackoverflow.com/q/23294658/3001761 — jonrsharpe, Oct 09 '16 at 19:55
@TheRedEmerald, you should include that in your post, and explain why it doesn't work for you. — Aurora0001, Oct 09 '16 at 19:56
Well that's just a *different* trivial duplicate: http://stackoverflow.com/q/15112125/3001761. Learn to do some research and [ask]. — jonrsharpe, Oct 09 '16 at 19:58

I'd recommend a while loop like so:

while Run not in ["Run", "stay", "1", "2"]:
    Run = input("not an option, try again:")

make the choice as `["1", "2"]` based on users code – Moinuddin Quadri Oct 09 '16 at 19:57
I'll try it out immediately. Thanks! – TheRedEmerald Oct 09 '16 at 19:57
also, could I use != instead of not in – TheRedEmerald Oct 09 '16 at 19:58
@TheRedEmerald no you couldn't, that would compare for equality not containment. – jonrsharpe Oct 09 '16 at 19:59
actually, `!=` would check whether `Run` was not equal to the whole list – Elliot Roberts Oct 09 '16 at 20:00
Uh, just ran this. And it works! Thanks! But just one tiny question, I put these before the if and elif script right, because right now it's giving me nothing as output even though I have an output that works if you choose option 1 or 2. – TheRedEmerald Oct 09 '16 at 20:02
Yup, I tried it out, it has to go before. Thanks :P – TheRedEmerald Oct 09 '16 at 20:04
