Python Download PDF from URL 2023.8.6

You can use the `requests` library to download a PDF. Here's a simple example: ```python import requests url = 'http://example.com/file.pdf' response = requests.get(url) with open('downloaded_file.pdf', 'wb') as f: f.write(response.content) ```

Yes, you need to install the `requests` library if it's not already installed. You can install it using pip: `pip install requests`.

Yes, you can loop through a list of URLs and download each file one by one. For example: ```python urls = ['http://example.com/file1.pdf', 'http://example.com/file2.pdf'] for url in urls: response = requests.get(url) filename = url.split('/')[-1] with open(filename, 'wb') as f: f.write(response.content) ```

You may need to include authentication in your request. For basic auth, you can add the `auth` parameter: ```python from requests.auth import HTTPBasicAuth response = requests.get(url, auth=HTTPBasicAuth('username', 'password')) ```

You can use try-except blocks to catch exceptions like HTTP errors or connection issues: ```python try: response = requests.get(url) response.raise_for_status() except requests.exceptions.HTTPError as err: print(f'HTTP error occurred: {err}') your code here... ```

Yes, the downloaded PDF file will retain all of its original formatting as it is saved in the same binary format.

You cannot directly display a PDF in Python, but you can open it with a PDF viewer or use libraries like PyPDF2 to manipulate it.

You can check the file size after downloading and compare it with the `Content-Length` header from the request to ensure it is complete.

You can specify the full path while opening the file for writing. For example, replace `downloaded_file.pdf` with `'/path/to/directory/downloaded_file.pdf'`.

For large files, it's recommended to stream the download using `stream=True` in your GET request and write chunks of data to avoid memory issues. ```python response = requests.get(url, stream=True) with open('large_file.pdf', 'wb') as f: for chunk in response.iter_content(chunk_size=8192): f.write(chunk) ```
