Step-by-Step Python and Postgres Tutorial with psycopg2

Video Description

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 Our Source Code https://github.com/hnasr/psycopg2/blob/master/db.py More details on the official site here http://initd.org/psycopg/docs/usage.html 🏭 Software Architecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🛰 Network Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQUBSgBXilKhRMJ1ACqr7pTr 🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC 🐘 Postgres Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWGrOqslniFlRcwxyY94cjj 🧮 Programming Pattern Videos https://www.youtube.com/playlist?list=PLQnljOFTspQV1emqxKbcP5esAf4zpqWpe 🛡 Web Security Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU3YDMRSMvzflh_qXoz9zfv 🦠 HTTP Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU6zO0drAYHFtkkyfNJw1IO 🐍 Python Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU_M83ARz8mDdr4LThzkBKX 🔆 Javascript Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWab0g3W6ZaDM6_Buh20EWM Enjoy guys!
