Here's my code.

```
a = [
        ['StarList', 'StarId38', 'ShipList']
    ]
b = [
        ['StarList', 'StarId3', 'ShipList'],
        ['StarList', 'StarId4', 'ShipList']
    ]
assert set(a) == set(b) # False

a = [
        ['StarList', 'StarId4', 'ShipList'],
        ['StarList', 'StarId3', 'ShipList']
    ]
assert set(a) == set(b) # True

```

It doesn't work:

```
Traceback (most recent call last):
    File "compare.py", line 8, in <module>
        assert set(a) == set(b) # False
TypeError: unhashable type: 'list'

```

Well, how to do it?
