Step-by-Step Python and Postgres Tutorial with psycopg2

Описание

In this tutorial, we will go through the basic steps on how to write a python script to read and write data on a Postgres database. We will start by describing what we have setup. I have a postgres instance running on a docker container which I will be using for this tutorial. You can watch this video that I made to learn how to spin up a postgres docker container https://www.youtube.com/watch?v=5QNL7_i-ay8 obviously you don’t have to use docker you can still instal postgres phsyically on your machine or if you have a server running postgres that should do the trick. We will then start from scratch as usual using visual studio code and python3. We will talk about the #psycopg2 library and how to install it. we will start by establishing a connection to postgres, we will talk about cursors, client-side cursors, server-side cursors the differences. Then we will execute a cursor to retrieve all rows in the table and display them. we will then insert a row to the database and commit the changes
