Scrape YouTube Comments

After executing the above piece of code, you need to open your web browser where your video is already opened. It will automatically perform Page Down and scrape comments, so you need to wait for the process to finish. The time taken by this step can vary depending on the number of comments on a video.

data = []
currentpagesource=youtube.get_page_source()
lastpagesource=''

while(True):
    if(lastpagesource==currentpagesource):
        break
        
    lastpagesource=currentpagesource
    response=youtube.video_comments()

    for c in response['body']:
        data.append(c)
        
    youtube.scroll()
    currentpagesource=youtube.get_page_source()

Constructing Dataframe

Now, we remove the duplicate data and convert our list to a dataframe. Then, we export our data to a CSV file.

df = pd.DataFrame(data)

df = df.replace('\n',' ', regex=True)

df = df[['Comment', 'Likes']].drop_duplicates(keep="first") 

df.to_csv('data.csv',index=False)

We check our data by using df.head() as shown below.

df.head()

Using a Proxy to Scrape Comments From YouTube

Youtube proxy is an intermediary server that provides data exchange between the device and the servers. It helps to create an indirect connection allowing you to bypass the firewall of your system administrator or Internet service provider. With the help of proxies, you can increase views on your Youtube videos and get more comments.

You need to open your command prompt and type the following.

$ git clone https://github.com/MShawon/YouTube-Viewer.git

$ cd YouTube-Viewer

$ pip install -r requirements.txt

Further, check your Google Chrome version and download the same version chromedriver.exe from https://chromedriver.chromium.org/downloads and place it in the chromedriver_win32 folder.

You need to filter the below command to filter good proxies if you’ve got a large proxy collection. Afterward, you have to use GoodProxy.txt for a proxy python file.

$ python proxy_check.py

Why Do You Need Proxies For YouTube Comment Scraping?

The several possible reasons to use a Youtube proxy are as:

  • Usually, at the management’s request, Youtube is often banned in educational institutions and office networks. So, you need a Youtube proxy to avoid bans and keep your access stable.
  • Some countries prohibit access to Youtube at the state level because its content does not comply with their national policies. It means no citizen can use Youtube within the country. So, you have to find a Youtube proxy provider with global IP addresses to unblock Youtube videos.
  • It will be quite hard for [people to scrape a large volume of data using data retrieval code or tools. To overcome this issue, we can employ high-bandwidth proxies that can allow the scraping of enormous volumes of data.
