To complete this task, follow these simple steps:

1. Understand the problem: You are given inputs i, j, and A, where i and j are integers and A is a list. Your goal is to return the sum of all the numerical elements in the list A between the positions i and j (including positions i and j). If no numerical element is present in the list, return 0.

2. Guidelines provided: 
   - i and j will be non-negative.
   - i and j will always have a value less than the length of A.
   - i will always be less than j.

3. Using the guidelines to find the answer:
   - Start by initializing a variable to store the sum, for example: total_sum = 0.
   - Iterate through the list A between the positions i and j using a loop. You can use the range() function with parameters i and j+1, as the ending index is exclusive.
     - For each element in the list, check if it is a numerical element. You can use isinstance(element, (int, float)) for that.
       - If the element is numerical, add it to the total_sum.
   - After iterating through all the elements between positions i and j, return the total_sum.

Here's an example using the input 1, 3, ['1729', 'a', 'I']:

1. Initialize total_sum = 0.
2. Iterate through the list A between the positions 1 and 3:
   - At position 1, the element is 'a', which is not a numerical element.
   - At position 2, the element is 'I', which is not a numerical element.
3. No numerical elements were found, so total_sum remains 0.
4. Return total_sum (in this case, 0).

Since no numerical elements were found between positions 1 and 3, the output is 0.<|im_end|>

 Sure, I'd be happy to help! Here's the task you've been given:

Task: Given inputs i, j, and A, where i and j are integers and A is a list, return the sum of all the numerical elements in the list A between the positions i and j (including positions i and j). Return 0 if no numerical element is present in the list between the given ranges. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.

Let's break down the task into simpler steps:

Step 1: Understand the inputs

* i and j are integers, and they represent the positions in the list A where we want to find the sum of the numerical elements.
* A is a list, and it contains the elements we want to sum.

Step 2: Identify the numerical elements in the list

* We need to identify which elements in the list A are numerical. In this case, we can see that '1729' and 'I' are numerical, but 'a' is not.

Step 3: Determine the range of numerical elements

* Since i is 1 and j is 3, we need to find the sum of the numerical elements in the list A between positions 1 and 3 (including positions 1 and 3).

Step 4: Sum the numerical elements

* We can sum the numerical elements in the list A between positions 1 and 3 as follows:
	+ '1729' + 'I' = 1729 + 1 = 1730

Step 5: Return the result

* Since we found a sum of 1730, we return 1730 as our output.

So, the output for the given inputs is 1730.

I hope this helps! Let me know if you have any questions or need further clarification.<|im_end|>
