Note:This post is just for educational purpose to show the use of Webscraping.

Have you ever been in a situation like, you are having you final exams in a week or so and you haven't attended a single lecture(I mean mindfully, of course)? Then you ask YouTube for help (happens in my case every time) and what you get is a huge(even larger than node_modules) playlist to watch and limited data/data-speed at your place.

Or like, you wanted to learn a new skill/language/framework from YouTube and you get a good "playlist" but limited storage space in your phone.

Now, there are websites/applications to download YouTube videos.
OOPS, either they download one video at a time or if they download a complete playlist at once, they are paid ones. You can download the playlist videos one-by-one(until that's a huge one). Exams are important, you can pay for them and if it is about learning, let it take some more time, we have entire life?

A Developer

Wait a minute, you are a Python developer. Why pay for a service you can build with a few lines of code?
This post will be about a simple project "YoPlaDo-YouTube Playlist Downloader" built using Python. We will be writing a program that takes the YouTube playlist link and web-scraps all the video links using BeautifulSoup and download the videos using Pytube.

Web Scraping

Have you ever searched and downloaded images? Or have ever Ctrl+ C and Ctrl+ V (If you know you know)? Or submitted an assignment with the solutions you get online? Basically, this is what scraping is.


Collecting data or to be more specific Extracting data from a website is Web-Scraping. Instead doing things manually, you can automate things. That's what a Web Scrapper does. You give it a list of things to extract and then it goes for shopping(scraping) from a website.
For example, you need an image, it searches for img tags.
These days Web-Scraping is being used in every fields staring from Digital Marketing to DataScience or AI.
So, various languages provide various libraries,frameworks and tools to make a Web Scraper or a Web Crawler. Python uses Beautiful Soup, Scrapy and a few more.
In this we will be creating a basic project with Beautiful Soup.

A Developer


Beautiful Soup

"Beautiful Soup is a Python package for parsing HTML and XML documents. It creates a parse tree for parsed pages that can be used to extract data from HTML, which is useful for web scraping." - Wikipedia

As mentioned, the library helps you extract and use data from websites.
I will explaining things in a simple way. For detailed information, you can go through the Docs.


"A pythonic library for downloading YouTube Videos." - Pypi

For detailed information, you can go through the Docs.

Coding Mode On

Let's get started,

We will be extracting links from a playlist(like https://www.youtube.com/playlist?list=) and download each video automatically with the program.This is just a basic project overview for beginners. You can go for documentation and make improvements.

- Import the libraries

If you want to followup with the post, you can take use "https://www.youtube.com/playlist?list=PLGzz7pyosmlJfx9ivigemSouoZR9uLT2-" as the input link as this is used in the below example. It will be easier to understand. Also make sure the playlist you use, should have videos which are downloadable and without any deleted videos. This problem can be solved using Exception block but in order to keep this post simple for beginners, the block hasn't been added.

Before importing make sure , you have downloaded the required libraires. You can use,

pip install pytube3
pip install beautifulsoup4

from pytube import YouTube
import bs4
import requests

Youtube from Pytube is used for playing with YouTube videos.
Bs4 is the Beautiful Soup used for webscraping.
Requests is the python HTTP library.

- Scraping all the videos links from the Playlist

url=input("Enter the Youtube Playlist URL : ") #Takes the Playlist Link
data= requests.get(url)

First we create an empty list "playlist" to store all the links to be extracted.

Now the url is taken as an input that is fed to requests.get().
Requests.get() sends a GET request to the specified url.

Then webscraping comes into play.
For simpler understanding, the line "soup=bs4.BeautifulSoup(data.text,'html.parser')"
brings you the HTML file of the website so that you can extract and process the data. You can use a parser of your choice("html.parser","lxml", "html5lib");they have their own advantages and disadvantages.

- Scraping(part 2)

for links in soup.find_all('a'):
        if (link[0:6]=="/watch" and link[0]!="#"):

For example, a playlist with 6 videos

Enter the Youtube Playlist URL : https://www.youtube.com/playlist?list=PLGzz7pyosmlJfx9ivigemSouoZR9uLT2-

soup.find_all('a') finds all the anchor tags from the extracted HTML file.
While looping through all the anchor tags links.get('href') finds all the video links present in the webpage.
The rest part of the code is for validation done to find only the link to the videos of the selected playlist. In the end you can see there are duplicate and unnecessary links, which are needed to be removed.

- Simple manipulation with the "playlist" list

del playlist[0:2]


This is added to remove some extra and duplicate links.
Note: set() will change the order of the videos. You can add your own code to remove duplicate links present in the list.

- Downloading Videos

vquality=input("Enter the video quality (1080,720,480,360,240,144):")

for link in playlist:
    yt = YouTube(link)
    videos= yt.streams.filter(mime_type="video/mp4",res=vquality)
    print(yt.title+" - has been downloaded !!!")

Alt Text

Note: Pytube updates have some bugs. Go for the documentation for updates in regex patterns. If you get KeyError:cipher, either the pytube hasn't been installed properly or there is a bug. Refer to https://stackoverflow.com/questions/56382295/getting-error-with-pytube-signature-cipher-get-signaturejs-streams-key

"vquality" is used to select the video quality you want to download.

Here comes the Pytube. Looping through the "playlist" list, each link is processed and downloaded using Pytube.

"yt" object stores the link and the "yt.streams.filter()" returns the filtered list as per the parameters given.
"video.download("Url to directory")" processes the link and downloads it to the mentioned directory.

Easy One

And with merely 30 lines of code, you saved a few dollars and gifted yourself a good project.
Well, for proper execution you can add your own exception blocks and logic. I would suggest you to go through the documentation.

Just a meme
For the application, you can go for the "dist" folder in the repository


Happy Scraping! Happy Coding.

That's my first technical blog. Do correct me if I am wrong. <3 <3 <3

Very cool exercise! Have you heard of the venerable youtube-dl project? It already supports playlists and many others. It’s written with python to boot!



Yep, that's a great-one. But pytube helps in understanding Webscraping better,so tried this approach.


Cool post! If you're on a mac, you can easily copy the link of a youtube video or a playlist and use youtube-dl, a command line tool to download videos on youtube.


Is downloading YouTube videos Legal ?


Although the post is for educational purpose, just to show Webscraping use,in the copyright infringement that surrounds certain YouTube videos, it is the uploader who is technically the copyright violator because he/she is publishing. So if you try to own a video that's illegal. Works fine till you keep things to yourself and that's too illegal. But YouTube hasn't taken any actions till date about it.


Really good post, thanks Trideep. Will definitely try it.



Cool alternative to youtube-dl. Thanks for creating this, will have to explore this down the road.


:) Thank you. Surely this could be improved in so many better ways.


Just because this post was for beginners just to make them acquainted with Webscraping and also that Beautiful Soup does the work in few lines and easier to understand.


Just so you know, it's actually spelled "web scraping," not "web scrapping."


So sorry about that and Thanks a lot.


No big deal. I'm just trying to help you out. You wrote a great article, so thank you for writing it.


You can also use a program called YouTube-DLG


That's a good choice. But I wanted to show the use of Webscraping in a project for beginners so I preffered pytube.


Hey. Is this still working? I don't know how you are using beautifulsoup to a playlist which depends upon javascript to form its page. I tried your code upto part-2 and it doesn't work.


Works for me. Javascript generates playlist but in the end every website is built with HTML files. You can go for the repository mentioned in the end.


Well look at the image I attached then. Also pytube isn't properly functional either. Its not updated and have multiple issues. A beginner might get more frustrated trying to debug.


Never knew that. Thanks for the information.


There is difference between, Browser downloading and You downloading manually using some software or code. :)


Really liked this tutorial, I was searching for something like this.
One question though, why are there duplicates in the "playlist" list?


You might have observed, that you can open a video by clicking the thumbnail or by clicking the title of the video. So there are two same links for each video. The scraper scraps both the links and thus that has a duplicate link in the "playlist". Later that can be corrected by just converting list to set. :)
