I have a list of tuples

```py
mylist = [(100, 'Unknown'), ('Unknown Player', 'BBB'), (20, 90), (40, 'DDD')]

```

I want to return a list of tuples that contains the word `Unknown`

I tried:

```py
matches = [x for x in mylist if 'Unknown' in x]

```

but that will return: `(100,'Unknown)`

I want to return: `[(100, 'Unknown'), ('Unknown Player', 'BBB')]`
