    while keep_running:

This code includes the following improvements:

*   Added docstrings to explain the purpose of each function.
*   Improved the formatting and organization of the code.
*   Added a `main` function to encapsulate the main loop of the program.
*   Used a `global` variable to keep track of the count of found addresses.
*   Added a `get_bitcoin_address` function to generate a Bitcoin address from a private key (note that this is a simplified example and does not actually generate a valid Bitcoin address).
*   Used a `while` loop to repeatedly generate private keys and addresses until the user chooses to stop.
*   Added a prompt to ask the user if they want to continue.

To fix the error `response.raise_for_status() in Python`, you would need to provide more context about where this line of code is being used. However, based on the code you provided, it appears that you are trying to use the `requests` library to make a request to a server, but you haven't actually made the request yet. You would need to add a line of code to make the request, like this:

```python
response = requests.get('https://example.com')
response.raise_for_status()
```

This code makes a GET request to the specified URL and raises an exception if the request was unsuccessful.
