I am trying to manually curate a dataset by going through each set and choosing whether or not to keep it or reject it. To do this, I want to plot a dataset, use the click module (https://click.palletsprojects.com/en/7.x/) to choose whether to keep it, then plot the next dataset and repeat. Currently, I am able to plot each set and choose whether or not to save it, but the problem is each graph remains above the next one. I need to go through thousands of datasets so it isn't viable to have them all plotted simultaneously.

I have a mammography image dataset (mini DDSM). These images show letter artifacts indicating left or right mamma and other useless information for my ML model, so I want to curate this dataset before training the model.

In this paper, Preprocessing of Digital Mammogram Image Based on Otsu’s Threshold, they use Otsu's binarization and opening on the mammography to clean the image (page 5 of 10):

Their results

So far, I have coded this:

Some background of what I am attempting to do is that, my backend /content route returns an array with id data in it such as:

I'm trying to process a folder full of data files of various formats and encodings. I no that building a generic process will require plenty of extreme cases to cover, but I do want to be able to address most files and folders. To address unknown encodings, I ran file -I *.csv on 4-5 sample folders to curate a list of the most common encodings. I then iterate the list in order to "guess" the right encoding for a certain file. Below is my code:

Hi Im trying to build a scraper (in Python) for the website ReelGood.com.

I am trying to extract linkedin url that is written in this format,

I have a table containing a user id, purchase amount, and date. I need to calculate the sum over several periods, for the same user. For example, given:

From an API, for the same user, I might need to sum and return all of the following ranges:

Some restrictions:

1. I don't know the dates up front (the consumer either needs calendar periods, or rolling periods), so I don't think I can create curated queries using SUM and CASE? I saw an example of this here.
2. I also need to use a stored procedure when interacting with the DB, so I wouldn't be able to dynamically create the SELECT statement from the API.

I don't have a lot of experiences writing SQL, but I imagine it's better to have a single query that calculates all of the totals than calculating the sums individually? Any suggestions?

I am trying to send a stylized email to a new customer once they submit a payment on my website. I read somewhere to try the render to string method which I did. The email triggers correctly, the only problem is that it doesn't seem to be using the email template. It's a basic plain text email.

Please see my code below. Any help on how to make this work would be great.
