Python save downloaded file

You will also learn to create a file downloader with a nice progress bar for your terminal using python. One of the most important and common programming tasks to perform on the web is downloading files from different online resources. A huge number of successful applications allow users to download files. So these are just a few web application functions that require downloading files:.

Using requests module is one of the most popular way to download file. So first of all you need to install requests module, so run the following command on your terminal. Now run this program and see what happens. Now run the above code and check your download folder, you will see the file has been downloaded.

And now its time to move another section of this tutorial that is how to download different types of files such as text, html, pdf, image files etc using python. It works but is not the optimum way to do so as it involves downloading the file for checking the header. So if the file is large, this will do nothing but waste bandwidth. I looked into the requests documentation and found a better way to do it. That way involved just fetching the headers of a url before actually downloading it.

This allows us to skip downloading files which weren't meant to be downloaded. To restrict download by file size, we can get the filesize from the Content-Length header and then do suitable comparisons. We can parse the url to get the filename. This will be give the filename in some cases correctly. However, there are times when the filename information is not present in the url. In that case, the Content-Disposition header will contain the filename information.

Here is how to fetch it. The url-parsing code in conjuction with the above method to get filename from Content-Disposition header will work for most of the cases. Use them and test the results. These are my 2 cents on downloading files using requests in Python. Let me know of other tricks I might have overlooked. Have a look at below code.
