I have a nested list mixed with list and numbers.

```
nested = [[1, 2, 3], [4, 5, 6], [7, 8], [9], 10, 11]

```

The nested lists only contain numbers, they'll never contain more lists.

Is it possible to write a list comprehension to make new list from the 'nested' list, producing the following output?

```
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]

```

This was my attempt( code is not working)

```
[num if isinstance(item, list) for num in item else item for item in nested]

```
