Question

Where is the optimal place to insert a print statement in the following code to debug it?

1 multiples = [] 2 3 for outer in range(1,3): 4 5 multiples.append([]) 6 7 for inner in range(1,3): 8 9 multiples[outer-1].append(inner) 10

Answer 1

The optimal place to insert a print statement in the given code to debug it is after line 9. This will help us identify any issues with the appending of values to the 'multiples' list.

Step-by-step explanation:

The optimal place to insert a print statement in the given code to debug it is after line 9. By inserting a print statement after line 9, we can see the values of the 'multiples' list after each iteration of the inner loop. This will help us identify any issues with the appending of values to the 'multiples' list.

Here's an example of how the code would look with the print statement:

1 multiples = []
2
3 for outer in range(1,3):
4
5 multiples.append([])
6
7 for inner in range(1,3):
8
9 multiples[outer-1].append(inner)
10 print(multiples)

This will print the value of the 'multiples' list after each iteration of the inner loop, allowing us to debug the code and see if the values are being appended correctly.
