Scraping YouTube Data Step-by-Step

Project Requirements

Here are the tools and libraries you’ll need for this project:

• Python 3.8 or newer – Make sure you have the latest version installed
• yt-dlp – For downloading YouTube videos
• ScraperAPI – To help with web scraping without getting blocked
• requests – A simple HTTP library for Python
• BeautifulSoup4 – For parsing HTML and extracting the data you need
• Json – For handling JSON data

Step 1: Setup Your Project

Let’s start by setting up your project environment. First, create a new directory to keep everything organized and navigate into it.

Open your terminal and run these commands:

mkdir youtube-scraper
cd youtube-scraper

Ensure you have Python installed on your system—Python 3.8 or newer is required. Now, let’s install the essential libraries for downloading and scraping YouTube data.

Use the following command to install the libraries:

pip install yt-dlp requests beautifulsoup4

With these steps, your project directory is ready, and you have all the necessary tools installed to start downloading and scraping YouTube data.

Now, let’s dive into the exciting part!

Step 2: Download YouTube Videos with Python

We’ll use the yt_dlp library to download YouTube videos. This library is a powerful tool for interacting with YouTube content with Python.

First, we’ll specify the URL of the YouTube video we want to download. You can replace the video_url variable with any YouTube video URL you wish to download.

from yt_dlp import YoutubeDL
 
video_url = "https://www.youtube.com/watch?v=xy5OQ2IWNtc"

After that, we’ll set up options for the downloader using a Python dictionary. In this snippet, we’ve specified two options:

• 'format': 'best': This option instructs the downloader to choose the best quality format available for the video
• 'outtmpl': '%(title)s.%(ext)s': This option specifies the output filename template. Here, %(title)s will be replaced by the title of the video, and %(ext)s will be replaced by the file extension (e.g., mp4, webm).

# Set options for the downloader
opts = {
    'format': 'best',  # Choose the best quality format available
    'outtmpl': '%(title)s.%(ext)s'  # Output template for the filename
}

Finally, we create a YoutubeDL object with the specified options and use it to download the video using the download() method. The method accepts a list of URLs as its parameter so you can download multiple videos simultaneously.

Now, here’s the complete code snippet:

# Create a YoutubeDL object and download the video
with YoutubeDL(opts) as yt:
    yt.download([video_url])

You can download the specified YouTube video with the desired quality and filename template by running this code snippet.

Step 3: Scrape YouTube Metadata

Important Note

The information provided here is for educational purposes only. This guide does not grant any rights to the videos or images, which may be protected by copyright, intellectual property, or other legal rights. Before downloading content, consult legal advisors and review the website’s terms of service.

Without downloading the video, we can use the yt_dlp library to get details about a YouTube video, like its title, size, channel, and language.

As an example, let’s scrape the details of this video using the extract_info() method, setting the download parameter to False so we don’t download the video again. The method will return a dictionary with all the information about the video.

Here’s a snippet for extracting the data:

from yt_dlp import YoutubeDL
 
video_url = "https://www.youtube.com/watch?v=xy5OQ2IWNtc"
opts = dict()
 
with YoutubeDL(opts) as yt:
    info = yt.extract_info(video_url, download=False)
    video_title = info.get("title")
    width = info.get("width")
    height = info.get("height")
    language = info.get("language")
    channel = info.get("channel")
    likes = info.get("like_count")
     
    data = {
        "URL": video_url,
        "Title": video_title,
        "Width": width,
        "Height": height,
        "Language": language,
        "Channel": channel,
        "Likes": likes
    }
    print(data)

To get more details about the video, you can use other keys from the dictionary returned by extract_info(). Here are some useful ones:

These keys will help you get all the information you need about a YouTube video.

Step 4: Scrape YouTube Comments

To scrape comments from a YouTube video, we’ll use the yt_dlp library to extract the comments without downloading the video itself.

In this example, we’ll be scraping the comments from this video: A brief introduction to Git for beginners

First, we import the YoutubeDL class from the yt_dlp library and specify the URL of the YouTube video we want to scrape:

from yt_dlp import YoutubeDL
 
# URL of the YouTube video
video_url = "https://www.youtube.com/watch?v=r8jQ9hVA2qs"

Next, we create an options dictionary opts with the key "getcomments" set to True. This tells yt_dlp that we want to extract comments:

# Options for YoutubeDL to get comments
opts = {
    "getcomments": True,
}

Using the YoutubeDL class with our specified options, we extract the video information, including comments, by calling the extract_info() method we used earlier.

Remember to set the download parameter to False so we only retrieve the metadata and comments without downloading the actual video:

# Extract video information, including comments
 
with YoutubeDL(opts) as yt:
    info = yt.extract_info(video_url, download=False)

Next, we use the get() method on the dictionary with the key "comments" to access the comments. We also retrieve the total number of comment threads using the key "comment_count":

# Get the comments
comments = info.get("comments")
thread_count = info["comment_count"]

Finally, we print the total number of comment threads and the comments themselves:

print("Number of threads: {}".format(thread_count))
print(comments)

Here is the complete code together:

from yt_dlp import YoutubeDL
 
# URL of the YouTube video
video_url = "https://www.youtube.com/watch?v=hzXabRASYs8"
 
# Options for YoutubeDL to get comments
opts = {
    "getcomments": True,
}
 
# Extract video information, including comments
with YoutubeDL(opts) as yt:
    info = yt.extract_info(video_url, download=False)
     
    # Get the comments
    comments = info.get("comments")
    thread_count = info["comment_count"]
     
    # Print the number of comment threads and the comments
    print("Number of threads: {}".format(thread_count))
    print(comments)

Step 5: Scrape YouTube Channel Information

To scrape information about a YouTube channel, we can use ScraperAPI to avoid getting blocked, the requests library to handle HTTP requests, and the BeautifulSoup library to parse HTML content.

We’ll scrape ScraperAPI’s YouTube channel’s “About” page and extract the channel name and description for this example.

First, we set up the API key for ScraperAPI and the URL of the YouTube channel’s “About” page.

Note: Don’t have an API key? Create a free ScraperAPI account and get 5,000 API credits to test all our tools.

We also define the parameters needed for the API request; the render parameter being set to true allows all Javascript on the webpage to be rendered fully:

api_key = 'YOUR_API_KEY'
url = f'https://www.youtube.com/@scraperapi/about'
params = {
    'api_key': api_key,
    'url': url,
    'render': 'true'
}

We then make a get() request to the ScraperAPI endpoint, passing in our parameters. This will allow us to bypass any restrictions and get the HTML content of the page:

response = requests.get('https://api.scraperapi.com', params=params)

If the request is successful (status code 200), we use BeautifulSoup to parse the HTML content and extract the channel’s name and description. We locate these elements using their specific HTML tags and classes we identified earlier:

  if response.status_code == 200:
  soup = BeautifulSoup(response.text, 'html.parser')
  channel_name = soup.find('yt-formatted-string', {'id': 'text', "class":"style-scope ytd-channel-name"})
  channel_desc = soup.find('div', {'id': 'wrapper', "class":"style-scope ytd-channel-tagline-renderer"})
  if channel_name and info:       
      channel_info = {
      " channel_name" : channel_name.text.strip(),
      "channel_desc" : channel_desc.text.strip(),
      }
  else:
      print("Failed to retrieve channel info")
else:
  print("Failed to retrieve the page:", response.status_code)

Finally, we print the extracted channel information:

print(channel_info)

Here’s the complete code all together:

import requests
from bs4 import BeautifulSoup
 
# API key for ScraperAPI
api_key = 'YOUR_API_KEY'
# URL of the YouTube channel's About page
url = 'https://www.youtube.com/@scraperapi/about'
# Parameters for the API request
params = {
    'api_key': api_key,
    'url': url,
    'render': 'true'
}
 
# Make a GET request to ScraperAPI
response = requests.get('https://api.scraperapi.com', params=params)
 
# If the request is successful, parse the HTML and extract the channel info
if response.status_code == 200:
    soup = BeautifulSoup(response.text, 'html.parser')
    channel_name = soup.find('yt-formatted-string', {'id': 'text', 'class': 'style-scope ytd-channel-name'})
    channel_desc = soup.find('div', {'id': 'wrapper', 'class': 'style-scope ytd-channel-tagline-renderer'})
 
    channel_info = {
        'channel_name': channel_name.text.strip(),
        'channel_desc': channel_desc.text.strip(),
    }
else:
    print("Failed to retrieve the page:", response.status_code)
 
# Print the extracted channel information
print(channel_info)

Using ScraperAPI makes it easy to retrieve web content, helping us to scrape data from websites like YouTube that may have restrictions.

ScraperAPI handles all the complexities of web scraping, such as managing IP rotation, handling CAPTCHAs, and rendering JavaScript, which can often block traditional web scraping techniques. Thus, we can focus on extracting the necessary data without worrying about these common issues.

For instance, YouTube often uses various mechanisms to prevent automated access, including rate limiting and complex page structures that require JavaScript rendering. By using ScraperAPI, we can effortlessly bypass these restrictions, allowing us to obtain data such as channel information, video details, and comments without being blocked.

How to Scrape YouTube Search Results

Scraping YouTube search results can provide valuable insights into popular content and trends related to specific keywords. In this example, we will use ScraperAPI to scrape the top YouTube search results for the query “scraperapi” and extract the videos’ titles and links.

First, we import the necessary libraries:

import requests
from bs4 import BeautifulSoup
import json

Next, we set up our ScraperAPI key and specify the search query. We also construct the URL for the YouTube search results page:

api_key = 'YOUR_API_KEY'
search_query = 'scraperapi'
url = f'https://www.youtube.com/results?search_query={search_query}'
params = {
    'api_key': api_key,
    'url': url,
    'render': 'true',
}

We initialize an empty list called video_data to store the extracted video information and make a request to the ScraperAPI endpoint with our parameters. This will allow us to retrieve the HTML content of the search results page:

video_data = []
response = requests.get('https://api.scraperapi.com', params=params)

If the request is successful (status code 200), we parse the HTML content using BeautifulSoup:

if response.status_code == 200:
soup = BeautifulSoup(response.text, 'html.parser')
videos = soup.find_all('div', {"id": "title-wrapper"})

We use soup.find_all() to find all div elements with the id of title-wrapper, which contain the video titles and links.

videos = soup.find_all('div', {"id": "title-wrapper"})

After that, we check if any video elements were found. If videos are found, we print the number of videos found and loop through each element to extract the title and link.

We get the title attribute of the anchor tag, which contains the video’s title, and the href attribute of the anchor tag, which contains the video’s relative URL. We concatenate them with the base URL “https://www.youtube.com” to form the full URL.

We then store the extracted title and link in a dictionary and append it to the video_data list.

if videos:
print(f"Found {len(videos)} videos")
 
for video in videos:
    video_details = video.find("a", {"id": "video-title"})
    if video_details:
        title = video_details.get('title')
        link = video_details['href']
        video_info = {"title": title, "link": f"https://www.youtube.com{link}"}
        video_data.append(video_info)

After extracting all video details, we save the video_data list to a JSON file for further use.

with open('videos.json', 'w') as json_file:
json.dump(video_data, json_file, indent=4)

Here’s the complete code all together:

import requests
from bs4 import BeautifulSoup
import json
 
# API key for ScraperAPI
api_key = 'YOUR_API_KEY'
# Search query for YouTube
search_query = 'scraperapi'
# URL of the YouTube search results page
url = f'https://www.youtube.com/results?search_query={search_query}'
# Parameters for the API request
params = {
    'api_key': api_key,
    'url': url,
    'render': 'true',
}
 
# Initialize an empty list to store video data
video_data = []
# Make a GET request to ScraperAPI
response = requests.get('https://api.scraperapi.com', params=params)
 
# If the request is successful, parse the HTML and extract video info
if response.status_code == 200:
    soup = BeautifulSoup(response.text, 'html.parser')
    videos = soup.find_all('div', {"id": "title-wrapper"})
     
    if videos:
        print(f"Found {len(videos)} videos")
        for video in videos:
            video_details = video.find("a", {"id": "video-title"})
            if video_details:
                title = video_details.get('title')
                link = video_details['href']
                video_info = {"title": title, "link": f"https://www.youtube.com{link}"}
                video_data.append(video_info)
         
        # Save the extracted video data to a JSON file
        with open('videos.json', 'w') as json_file:
            json.dump(video_data, json_file, indent=4)
    else:
        print("No videos found")
else:
    print("Failed to retrieve the page:", response.status_code)
