What will be the output of the following Python code?datavalues = [1, 2, 3, 4] datavalues.append([5,6,7,8]) print(len(datavalues))Options48125

Break Down the Problem

1. Identify the list datavalues and its initial content.
2. Analyze the effect of the append method on the list.
3. Determine the final length of the list after the operation.

Relevant Concepts

• The append method in Python adds an item to the end of a list.
• The len function returns the number of items in a list.

Analysis and Detail

1. Initial List:

   • datavalues = [1, 2, 3, 4] (length is 4).

2. Using append:

   • The code datavalues.append([5,6,7,8]) adds the entire list [5, 6, 7, 8] as a single new element to datavalues.
   • After this operation, datavalues looks like this: [1, 2, 3, 4, [5, 6, 7, 8]].
   • Note that the list [5, 6, 7, 8] is treated as one item.

3. Calculating Length:

   • The new length of datavalues is now 5 (the original four numbers plus one list).

Verify and Summarize

• The final list contains five elements: four integers and one list.
• The len(datavalues) returns 5.

Final Answer

The output of the code will be 5.
