Question
![**Question 4**
Explain what the following line of code is doing:
```python
items = ['A', 'B', 'C']
for item in items:
```
**Question 5**
What will be the result of this line of code? Why?
```python
list1 = ['A', 'B']
list2 = [1, 2, 3]
for item1 in list1:
for item2 in list2:
print(item1, item2)
```
**Explanation:**
- The code in Question 5 uses nested loops to iterate over two lists: `list1` and `list2`. For each element in `list1`, it iterates over all elements in `list2`, printing each pair.
- The result will be:
```
A 1
A 2
A 3
B 1
B 2
B 3
```
- This occurs because for each element `A` and `B` from `list1`, the inner loop goes through all elements in `list2` (1, 2, 3). Each combination is printed on a new line.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F48fa6f50-a510-4234-9950-4191a13ca9b5%2F5012e70f-b536-4e5a-9f2f-164e156ff2bd%2F862tvph_processed.jpeg&w=3840&q=75)
