![**Title: Understanding Nested Loops in Python**
**Introduction:**
This educational section explores how nested lists work in Python and demonstrates how different loops interact with these structures. We will look at two code snippets (2A and 2B) to understand their output when executed.
**Code Snippet 2A:**
```python
nested = [[3, 4, 5], [8, 9, 10]]
for i in range(len(nested)):
print(nested[i])
```
**Explanation 2A:**
- The variable `nested` is a list containing two inner lists: `[3, 4, 5]` and `[8, 9, 10]`.
- The `for` loop iterates over each inner list within the `nested` list.
- For each iteration, `print(nested[i])` outputs the entire i-th inner list.
**Output 2A:**
```
[3, 4, 5]
[8, 9, 10]
```
**Code Snippet 2B:**
```python
nested = [[3, 4, 5], [8, 9, 10]]
for i in range(len(nested)):
for j in range(len(nested[i])):
print(nested[i][j])
```
**Explanation 2B:**
- Similar to 2A, `nested` is a list containing two lists.
- The outer loop iterates over each inner list.
- The inner loop iterates over each element in the current inner list.
- `print(nested[i][j])` outputs each element of the inner lists individually.
**Output 2B:**
```
3
4
5
8
9
10
```
**Conclusion:**
By comparing these code snippets, you can see how accessing and printing elements differs between iterating over lists and nested lists. This demonstrates crucial concepts in handling complex data structures like nested lists in Python.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F10732faa-f9b7-4c12-81f1-19b5d255f419%2F8f469793-0605-4064-ae3b-eb55f7f02561%2Fm4se6e_processed.png&w=3840&q=75)
