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?

...ANSWER
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 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
QUESTION
I am building an order form that limits how many items you can order based on the stock of the item. I have a menu collection which has items
ANSWER
Answered 2021-Jun-10 at 20:49You should deffinitely use a cloud function to update the stock. Create a function onCreate and onDelete functions trigger. If users can change data you would also need to onWrite function trigger.
Depending on the amount of data you have you woould need to create a custom queue system to update the stock. Belive me! It took me almost 2 years to figure out to solve this. I have even spoken with the Firebase engeeners at the last Firebase Summit in Madrid.
Usualy you would use a transaction to update the state. I would recommend you to do so if you don't have to much data to store.
In my case the amount of data was so large that those transactions would randomly fail so the stock wasn't correct at all. You can see my StackOverflow answer here. The first time I tought I had an answer. You know it took me years to solve this because I asked the same question on a Firebase Summit in Amsterdam. I asked one of the Engeeners who worked on the Realtime Database before they went to Google.
There is a solution to store the stock in chunks but even that would cause random errors with our data. Each time we improved our solution the random errors reduced but still remained.
The solution we are still using is to have a custom queue and work each change one by one. The downside of this is that it takes some time to calculate a lot of data changes but it is 100% acurate.
Just in case we still have a "recalculator" who recalculates one day again and checks if everything worked as it should.
Sorry for the long aswer. For me it looks like you are building a similar system like we have. If you plan to create a warehouse management system like we did I would rather point you to the right direction.
In the end it depends on the amount of data you have and how often or fast you change it.
