You can escape these characters using a backslash \.
QUESTION
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?

Answered 2021-Jun-15 at 20:43YouTube 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:

QUESTION
I am writing a program in python to have a user input multiple websites then request and scrape those websites for their titles and output it. However, when the program surpasses 8 websites the program crashes every time. I am not sure if it is a memory problem, but I have been looking all over and can't find any one who has had the same problem. The code is below (I added 9 lists so all you have to do is copy and paste the code to see the issue).
...ANSWER
Answered 2021-Jun-15 at 19:45To avoid the page from crashing, add the user-agent header to the headers= parameter in requests.get(), otherwise, the page thinks that your a bot and will block you.
QUESTION
I'm doing some scraping, but as I'm parsing approximately 4000 URL's, the website eventually detects my IP and blocks me every 20 iterations.
I've written a bunch of Sys.sleep(5) and a tryCatch so I'm not blocked too soon.
I use a VPN but I have to manually disconnect and reconnect it every now and then to change my IP. That's not a suitable solution with such a scraper supposed to run all night long.
I think rotating a proxy should do the job.
Here's my current code (a part of it at least) :
...ANSWER
Answered 2021-Apr-07 at 15:25Interesting question. I think the first thing to note is that, as mentioned on this Github issue, rvest and xml2 use httr for the connections. As such, I'm going to introduce httr into this answer.
The following code chunk shows how to use httr to query a url using a proxy and extract the html content.

QUESTION
I am trying to scrape data of a match played between United and Sheffield United yesterday night in the premier league from understat.com. My goal is to fetch "shots per game". If you see understat.com, it has a match id for all the matches and I am using that match id to scrape the data using BS4 and requests. I have successfully located the class and got the raw data that I need to fetch in JSON format but it's giving me an error like "json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)". Below is my code:
...ANSWER
Answered 2021-Feb-10 at 17:22The 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

I've created a vba script in combination with selenium to scrape price $8.97 from this webpage. The script does fetch the content if I run it in non-headless mode. However, my intention is to grab the content in headless mode. I know I can use their api to fetch the price but the very api gets blocked after 4/5 requests, so I intentionally chose this route.
I've tried with (works in non-headless mode):

Answered 2021-Jun-01 at 17:54You need to wait also properly to get the text, even though your css looks good.
Or you could set a timeout on the page loading :
QUESTION
I'd like to dynamically update one column value in a table based on the user input in a different column. The user-editable column is quantity, and I'd like to multiply that by a price value (id = 'pmvalue') to display total price (id 'totalpmvalue') as an output.
I don't understand what javascript to use here - I've tried searching for solutions online, but haven't been able to find something that exactly corresponds to my use case (and I'm not experienced enough to understand how to adapt solutions for slightly different use cases). Any tips are greatly appreciated!
Here's my code:
...ANSWER
Answered 2021-Jun-14 at 20:12If you are going to have multiple rows, you should be using class, not id, the id attribute needs to be unique in a document.
