I have a dataframe like this:

I have a class hierarchy like bellow:

I have no clue if what I'm trying to do is possible in PostgreSQL. But here we go: I want to pass an array of strings to a function. Then I want to iterate through this array and want to SELECT data from a table based on the current string.

The selected data should be pushed to a new array(or table?) which is returned when the iteration is finished.

Here is a simplified version of what I'm trying to do in JavaScript:

I'm trying to receive stock data for about 1000 stocks, to speed up the process I'm using multiprocessing, unfortunately due to the large amount of stock data I'm trying to receive python as a whole just crashes.

Is there a way to use multiprocessing without python crashing, I understand it would still take some time to do all of the 1000 stocks, but all I need is to do this process as fast as possible.

I have a program that takes sheets of mixed data from an Excel file and places it into a SQL Server Database. It already runs relatively fast, but I wish to make it more dynamic. Currently, I use OleDb to select data from an Excel file and Entity Framework Core to add the data to a SQL Server Database.

I have a class for each sheet in the Excel file. The class I'm going to use as an example here is my vHost class. After I use OleDb to select all the data from the vHost Excel sheet (using SELECT *) I place the data into a Data Table object. I then go through each column in the Data Table to create a List object of the column names in the Excel sheet. These are crucial for the program to understand where to insert data into the SQL Server Database. Once the list of column names is created, the program then indexes through all the data in the Data Table and creates a vHost object to place in the SQL Server Database. This is the portion that I wish to make more dynamic.

In order for the program to decide what object in the vHost class to set some data equal to, it compares an index in the Column List to a static string. If the column index we are on is equal or contains the same string for the column name, the object correlating to that in the vHost class is set equal to some data. This portion is long and grueling to type, but it allows me to create a program that will run with minimal errors.

Here is the code I have for the vHost section:

Here are the codes that I use:

I have seen a few posts about this but I've struggled to find an answer that works for me. I am trying to get the race result time to display in HH:MM:SS which is currently in milliseconds in the table

I have a class in my django models as below:
