The output of the code will be 4.

Here's the step by step explanation:

1. We start with a list `list1` that contains three elements: 1, 2, and 3.

2. Then, we append another list `[4, 5, 6]` to `list1`. After this operation, `list1` becomes `[1, 2, 3, [4, 5, 6]]`.

3. When we print the length of `list1` using the `len()` function, it counts the number of elements in the list. In this case, there are four elements: 1, 2, 3, and the appended list `[4, 5, 6]` (which is considered as one element).

So, the output will be 4.
