-### Complex filter function using lambdas
-
-```py
-def update_entries(old, new):
-    """Merge old and new data, removing dupes"""
-    combined = old + new
-    seen = set()
-
-    filter_func = lambda x: not (tuple(x) in seen or seen.add(tuple(x)))
-
-    unique_combined = list(filter(filter_func, combined))
-```
-
-#### ChatGpt explanation
-
-Certainly, the line
-
-```python
-filter_func = lambda x: not (tuple(x) in seen or seen.add(tuple(x)))
-```
-
-creates a lambda function that takes a single argument `x`, where `x` is
-expected to be a list. The function converts `x` to a tuple and checks for its
-existence in the `seen` set.
-
-Here is a breakdown of the logic:
-
-1. `tuple(x)`: This converts the list `x` to a tuple because lists are
-   unhashable and cannot be stored in a set. Tuples, being immutable, can be
-   stored in a set.
-
-2. `tuple(x) in seen`: This checks whether the tuple form of `x` is already in
-   the `seen` set.
-
-3. `seen.add(tuple(x))`: This adds the tuple form of `x` to the `seen` set. The
-   `add` method of a set returns `None`.
-
-4. `tuple(x) in seen or seen.add(tuple(x))`: This combines the above two steps.
-   The `or` operator returns the first "truthy" value it encounters, or the last
-   value otherwise. Since `seen.add()` returns `None`, which is "falsy," this
-   part will return `True` if `tuple(x)` was already in `seen`, and `None`
-   otherwise. Importantly, if `tuple(x)` was not already in `seen`, it will be
-   added.
-
-5. `not (...)`: The `not` negates the result. So if `tuple(x) in seen` was
-   `True`, `not True` would be `False`, causing the filter to skip this item. If
-   `tuple(x) in seen` was `False`, `not None` would be `True`, causing the
-   filter to include this item and also adding it to `seen`.
-
-In summary, the lambda function acts as a filter that only returns `True` for
-the first occurrence of each unique list `x`, after converting it to a tuple for
-hashability and set membership tests. After a unique list has been seen once,
-any subsequent occurrences will cause the lambda function to return `False`,
-effectively filtering them out.
