Database programming in python pdf

Can you create a database using Python?
We have learned how to use Python and MySQL Connector to create an entirely new database in MySQL Server, create tables within that database, define the relationships between those tables, and populate them with data.
We have covered how to Create, Read, Update and Delete data in our database..
What is Python database?
Python supports various databases like SQLite, MySQL, Oracle, Sybase, PostgreSQL, etc.
Python also supports Data Definition Language (DDL), Data Manipulation Language (DML) and Data Query Statements.
The Python standard for database interfaces is the Python DB-API..
What is the definition of a database in Python?
A database is an abstraction over an operating system's file system that makes it easier for developers to build applications that create, read, update and delete persistent data..
Which database is best for Python programming?
10 Best Databases for Python Projects
1. SQLite.
2. MySQL
3. PostgreSQL
4. MongoDB
5. Redis
6. Cassandra
7. DynamoDB
8. Elasticsearch
Python being a high-level language provides support for various databases.
We can connect and run queries for a particular database using Python and without writing raw queries in the terminal or shell of that particular database, we just need to have that database installed in our system.

Does Python need a database driver?

Programming languages like Python need a special driver before they can speak to a database from a specific vendor

These drivers are typically obtained as third-party modules

The Python Database API (DB-API) defines the standard interface with which all Python database drivers must comply

These details are documented in PEP 249

The general workflow of a Python program that interacts with a MySQL-based database is as follows: Connect to the MySQL server

Create a new database

Connect to the newly created or an existing database

Execute a SQL query and fetch results

Inform the database if any changes are made to a table

Close the connection to the MySQL server

Here is the list of available Python database interfaces: Python Database Interfaces and APIs

You must download a separate DB API module for each database you need to access

For example, if you need to access an Oracle database as well as a MySQL database, you must download both the Oracle and the MySQL database modules

Python MySQL Connector is a Python driver that helps to integrate Python and MySQL
