            The problem is that your CSS selectors include parentheses () and dollar signs $. These symbols already have a special meaning. See:

            You can escape these characters using a backslash \.

            Beautfiul Soup HTML parsing returning empty list when scraping YouTube
            Asked 2021-Jun-15 at 20:43

            I'm trying to use BS4 to parse through the HTML for an about page on a youtube channel so I can scrape the number of channel views. Below is the code to scrape the channel views (located in the 'yt-formatted-string') and also the whole right column of the page. Both lines of code return either an empty list and a "None" value for the findAll() and find() functions, respectively.

            I read another thread saying I may be receiving an empty list or "None" value because the page is accessing an API to get the total channel views to count and the values aren't actually in the HTML I'm parsing.

            I know I could access much of this info through the Youtube API, but I want to iterate this code over multiple channels that are not my own. Moreover, I want to understand how to use BS4 to its full extent so I can replicate this process on an Instagram page or Facebook page.

            Should I be using a different library that isn't BS4? Is what I'm looking to accomplish even possible?

            YouTube is loaded dynamically, therefore urlib won't support it. However, the data is available in JSON format on the website. You can convert this data to a Python dictionary (dict) using the built-in json library.

            This example is using the URL you have provided: https://www.youtube.com/c/Rozziofficial/about, you can change the channel name, it will work for all channels.

            Here's an example using requests, you can use urlib instead:

            The problem is your json_data as a string starts with the '{. The start index you want is actually one more index value ahead at the {, so you want to add 2, not 1 to the index start:

            index_start = strings.index("('")+2 instead of index_start = strings.index("('")+1

            After some discussion in the comments below, my original answer isn't going to cut it.

            The structure of the file Test.csv is not something that DictReader from the CSV module can parse. This is easily solved by creating a simple file parser.

            The part below the 2 methods has not changed much. Instead of parsing the results of DictReader from the CSV module, we parse the results from the function readcsv
