The `download` library provides a simple, high-level function for downloading files from the internet, including optional extraction of zip archives. It's built on `urllib.request` and offers progress bars via `tqdm`. The current version is 0.3.5, and it maintains a relatively stable API with infrequent releases.

The quickstart demonstrates the core functionality of downloading a file from a URL to a specified directory. It uses `download.download()` with `verbose=True` for progress and `replace=True` to ensure idempotency. The library also supports `extract=True` for automatic unzipping of archives.
The recommended fix is to ensure the target server has a valid SSL certificate. If this is not possible and you understand the security implications, you might need to globally or contextually bypass SSL verification using Python's `ssl` module, which is outside the direct scope of the `download` library's API.
To ensure that existing files are always updated, explicitly set the `replace=True` argument when calling `download.download()`.
Ensure the user running the Python script has write permissions to the specified output directory. Pre-creating the directory with `os.makedirs(path, exist_ok=True)` can help isolate permission issues. Handle `PermissionError` or `IsADirectoryError` if encountered.
Install the library using pip: `pip install download`.
Ensure you are calling the function correctly: `from download import download` then `download(...)` OR `import download` then `download.download(...)`. Verify no local files named `download.py` are interfering.
Confirm the server's certificate is valid. If you control the server, update the certificate. If this is a known issue for an internal server, you might need to explore options to manage SSL contexts, but disabling verification is a security risk.
Run your Python script with a user account that has write access to the target directory. Alternatively, specify an output directory where write permissions are granted (e.g., a temporary directory or a user-specific folder).
