Question
The provided code segment is designed to continuously take user input and append it to a list as long as the input is a positive integer.

**Code Description:**

```python
user_numbers = []
user_input = int(input())
while user_input > 0:
    user_numbers.append(user_input)
    user_input = int(input())
```

**Explanation:**

- The code initializes an empty list `user_numbers`.
- It then prompts the user for input using `input()` and converts it to an integer with `int(input())`. This value is stored in `user_input`.
- A `while` loop checks if `user_input` is a positive number (`user_input > 0`).
- If true, the input is appended to the `user_numbers` list.
- The code then prompts the user for another input. This process repeats until the user enters a non-positive number, terminating the loop.

**Question:**

What does the above code do?

- Prints numbers
- Fill-in the empty list with the user input
- Generates a list of 10 numbers
- None

**Correct Answer:**

- Fill-in the empty list with the user input

The code appends positive user inputs to the list until a non-positive number is entered.
