· Download with multithreading. Create a text file called “url_bltadwin.ru” and paste all the URLs you got, and create another python file in the same folder. We . The download program above can be substantially speeded up by running them in parallel. The following python program shows how to download multiple files concurrently by using multiprocessing library which has support for thread pools. Note the use of results list which forces python to continue execution until all the threads are complete. I started downloading it single file at a time, however it's taking a very long time. Is there a way to spawn some multi-threaded processes to download maybe a batch of files simultaneously. Probably like process1 downloads the first 20 files in the folder, process2 downloads the next 20 simultaneously and so on. Right now, I'm doing as follows:Reviews: 2.
Threads are a way to run several program parts at once, see for instance An Intro to Threading in Python. Multi-threaded downloads are a good option in order to make a more efficient use of the Internet connection. The threads download pages as they go. Read bltadwin.ru files, filter your URL list accordingly and care for crawl delay. Python provides different modules like urllib, requests etc to download files from the web. I am going to use the request library of python to efficiently download files from the URLs. Let's start a look at step by step procedure to download files using URLs using request library−. 1. Import module import requests 2. Get the link or url. Output: Time taken: This is a sane example and the code will open each URL, wait for it to load, print its status code and only then move on to the next URL. This kind of code is a very good candidate for multi-threading. Modern systems can run a lot of threads and that means you can do multiple tasks at once.
