l = [1,2,3,4,5,6]l.append([a,b,c,d,e,f,g,h,i,j,k])print(len(l))What will be the output of this code in python

To understand the output of the provided Python code, let's analyze it step by step.

1. List Initialization: The variable l is initialized as a list containing six integer elements: [1, 2, 3, 4, 5, 6].

2. Appending a List: The append method is used to add a new item to the end of the list. In this case, the item being added is another list: [a, b, c, d, e, f, g, h, i, j, k]. This item is a list that contains 11 elements (assuming a, b, ..., k are to be treated as separate elements).

3. Length Calculation: After the append operation, the list l will have one new item, which is the entire list [a, b, c, d, e, f, g, h, i, j, k]. Therefore, the new l becomes: $l = [1, 2, 3, 4, 5, 6, [a, b, c, d, e, f, g, h, i, j, k]]$ Here, the original six integers are still present, and the appended list counts as a single element.

4. Calculating Length: Finally, len(l) will count the number of top-level elements in the list. After appending, there are 7 elements in l (six integers and one list).

Final Answer

The output of the code print(len(l)) will be:
