Is there a way to check if an item exists in a Python tuple?

Question

I have seen an `index` function but it says it errors out if it can't find it. Is there a simple way to just check if the item exists? I just want to get a boolean value of the result so like: ``` if tuple.exists("item"): print "it exists" ```

Accepted Answer

Use `in` operator:

```
>>> 2 in (2, 3, 4)
True
```

`in` operator can be used to check for the membership of any element in a sequence.

And don't name your tuple as `tuple`. Use a different name.
