Day 26 of learning python as a beginner. Topic: CRUD operations in python postgreSQL. I had tried to explore SQL database handling in python and someone suggested me that I should also try performing CRUD (Create, Read, Update and Delete) operations in it. Although I have performed CRUD using the code however it was my first time doing the same by using a SQL database. While programming I was getting ideas of using try except (error handling), using match case (for selection of operation) however I decided to stick to CRUD only for now. I created four functions to perform each operations and used with keyword which someone has suggested me. Some of the SQL keywords I used are as follows: 1. INT PRIMARY KEY: this means that the type of value will be an integer and the primary key means that it is necessary for it to be entered. 2. VARCHAR: you can call it like a string as it can take data with strings, integers, special characters etc. 3. CHAR: this is a one word character which I used to enter the value of gender. And here's my code and its result in both console and database.
