Hi everyone!
Please be warned, I am a doctoral candidate who realized that there is no way around learning how to use Python, but I have come accross numerous roadblocks where I hope you may be able to help?
I have managed to scrape/crawl Twitter feeds of selected users, but now I am looking to extract all articles from wordpress pages (excl. images), including primarily the following:
- Title
- Article Link
- Time & Date
- Text
Optimally as an output within CSV / Excel.
I have come accross the following website:
https://indianpythonista.wordpress.com/2...iful-soup/
https://www.digitalocean.com/community/t...d-python-3
https://zach-adams.com/2015/04/python-sc...wordpress/
But truly am struggling to get any of these codes, in all of its variants to work. (Scrapy wont install on my PyCharm, so I resorted to BeautifulSoup.)
A sample of websites I want to scrape (particularly subsections may include infite scrolling):
1) https://electrek.co/guides/tesla/
2) https://www.teslarati.com/tag/tesla/
Is there one of you out there who would be able to give a hand to amend on of the beaoutiful-soup scripts to the above 2 sample pages? I would take it from there and use it on any other wordpress blogs, but I guess I need a starting hand!
Appreciate your time! Have a great weekend and stay safe.

Take a look at part-1 and part-2.

Here is a start without using Selenium,you would probably have struggle to figure this way of doing it 
So the infinity scrolling part return whole page in json,the can take data from dictionary and parse if return HTML with BeautifulSoup.

Thank you soooo much for your suggestion/code here! I will give it a try and come back should I hit a few more walls a long the way.
Really appreciate it!
If any other suggestions come into mind, please do not hesitate to fire them across.
Wish everyone a fantastic start to the week!
Regards

I just tested it using the code provided, but it produced no results oddly enough.
I ensured to have installed all the packages. Am I missing something? :(

Simple troubleshooting is to print json_data.
So on line 89 add:
print(json_data) Now only use Requests that give back the json data.
Test now again and it works for me.
Here in a other environment not mine Notebook,as you see it work there to.

Feel free to try my Wordpress blog scraper code that I used for my own blog.
I wrote this in 2018 so I don't remember much about how it worked:
