craigslist | Python script to scrape craigslist RSS feed

first post on SO, let me know how I can improve my question.

Goal: My app is a Craigslist scraper, it finds new posts and sends the feed to the user's email. It has a main thread that always listens to requests, and a worker thread, managed by the main thread, and is either working or sleeping.

Expected vs Actual Results: As mentioned in the title, the app works fine in the container locally, but when it's hosted on Cloud Run, the output and side-effects of the worker thread are deferred until the worker thread is killed.

It seems like the worker thread is only started when the main thread calls to kill it, at which point the worker thread only does one iteration of its work and then kills itself.

No errors messages.

Please let me know what additional information would help.

I am building a web app with Flask. It is the dashboard of my marketing software. In my marketing software, users can create some campaigns.

In a campaign, there are several tasks. When a user wants to edit a task, I get this "Internal Server Error" page.

When I check the log, I can see this error:

I'm learning Pools and just want to scrape Craiglist and to have an array of titles. I have written the program that generally works (did various tests) but in the end results in printing empty array.

Here is my code:

Background

I have a large dataset in SAS that has 17 variables of which four are numeric and 13 character/string. The original dataset that I am using can be found here: https://www.kaggle.com/austinreese/craigslist-carstrucks-data.

1. cylinders
2. condition
3. drive
4. paint_color
5. type
6. manufacturer
7. title_status
8. model
9. fuel
10. transmission
11. description
12. region
13. state
14. price (num)
15. posting_date (num)
16. odometer (num)
17. year (num)

After applying specific filters to the numeric columns, there are no missing values for each numeric variable. However, there are thousands to hundreds of thousands of missing variables for the remaining 14 char/string variables.

Request

Similar to the blog post towards data science as shown here (https://towardsdatascience.com/end-to-end-data-science-project-predicting-used-car-prices-using-regression-1b12386c69c8), specifically under the Feature Engineering section, how can I write the equivalent SAS code where I use regex on the description column to fill missing values of the other string/char columns with categorical values such as cylinders, condition, drive, paint_color, and so on?

Here is the Python code from the blog post.

I'm trying to append a value to a DynamoDB table entry:

This is my code in Jupyter-Lab:

I am using VS Code with a prettier extension added. I try to write a line that contains a "href" like this:

I am working on a web app, and i am having some issues with reactJS Router. When i redirect to the /sell path the HTML form the / path stays, and the HTML inside the /sell route doesn't load.

Am i doing something wrong? would anyone be able to point me towards the right direction?

I'm having an issue where the code I'm scraping is only printing out the first entry of each page. What I require is that all the data from all three pages of the website get scraped and added to the list 'infoList'.

What I assume is the problem the declaration 'CAR_INFO = 0' but I'm not sure how to fix it. Any tips or push in the right direction would be greatly appreciated.
