How Postgres Triggers Can Simplify Your Back End Development
For Django there's https://github.com/Opus10/django-pgtrigger that makes it possible to define triggers right in your models, so you have everything in one place.

A lightweight alternative to Celery for Django-PostgreSQL apps.
Note that have now ditched our post_save signal from the previous solution. As we pointed out, signals can easily be missed. Instead, we are using a Postgres trigger : defining the listener as it is above makes use of the django-pgtrigger library to write a Postgres trigger to our database, the job of which is to notify our channel whenever a Comment is inserted in to the database. Triggers are far more robust than signals for detecting database write events; application level triggers can easily be missed, whereas triggers will always be executed.

Can I learn Python while practicing writing queries for SQL simultaneously? I've recently completed learning SQL and trying to get better at it.
You can practice both by using https://www.psycopg.org from your Python code to communicate with your database. When I wanted to practice some SQL, that's what I did (we use psycopg at work, so that's what I practiced with, making a dream journal thingy for myself that was better than just noting stuff in a notepad because I could then look up e.g. what other stuff was correlated with Y, how many times I dreamed of X, etc. etc.)

Installing psycopg2==2.8.6 throws an error
But seems like it should work with Django 3, which you have specified https://github.com/psycopg/psycopg2/issues/1293

Uploading CSVs to a SQL table using Python
If you're using Postgres for your SQL, look at the "copy' method of the psycopg module (see https://www.psycopg.org/articles/2020/11/15/psycopg3-copy/) . It's much faster than INSERTs in my experience (YMMV).

Underappreciated Challenges with Python Packaging
Back when I used Psycopg2, there was no -binary package, so you'd get libpq set up similarly to pg-native. Docs say:
> The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.
Relevant GitHub discussion: https://github.com/psycopg/psycopg2/issues/674
I dunno, this seems worse to me.

Why "import blescan as blescan"?
I sometimes do this in testing. For example, consider the library used to communicate with a Postgres database, psycopg.
