I tried to find the available methods but couldn't find it. There is no contains. Should I use index? I just want to know if the item exists, don't need the index of it.

Thanks, for multiple elements should I do if a in tuple and b in tuple: ? –  Joan Venge Jul 29 '13 at 9:20
    
Yes. If you have a lot of elements you might consider using sets instead, where you can do union, difference and intersection operations. –  Lennart Regebro Jul 29 '13 at 9:23
    
Thanks, actually the API I am using is returning a tuple, that's why I was using that. Should I convert it to a set? –  Joan Venge Jul 29 '13 at 9:23
    
@JoanVenge: If you want it to be a set, yes. –  Lennart Regebro Jul 29 '13 at 9:24
    
Thanks will do. I just didn't want to change the data types too much because it's gonna get called 10000s of times every frame. –  Joan Venge Jul 29 '13 at 9:29
