Decode/Encode, as well as writing operations should be fixed depends on the target data type. There is also a nice Python module named wget that is pretty easy to use. When the files of 0 size are returned it could be the server limiting number of requests but I still would like to explore if there is a possibility of downloading multiple files using wget and asyncio. There is an answer to download multiple files using multiprocessing here.

We make use of the wget command to download data directly from the web with a download link ad. I have utilized the following code earlier for scraping websites but not for downloading files. In this video, we use python to fetch data from the internet. I tried the answer here but most of the files are of size 0.īut when I simply looped using wget(see below), I got complete files. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP. Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. The name comes from the word 'World Wide Web' and the word ' Get '. A user agent is a computer program representing a person, for example, a browser in a Web context.
