The easiest way to install is by using Python Package Manager, pip. This utility is bundled with standard distribution of Python. Using the above command, we can download the latest released version of SQLAlchemy from python.org and install it to your system.
To check which version of sqlalchemy is installed, use pip show sqlalchemy or pip3 show sqlalchemy in your CMD/Powershell (Windows), or terminal (macOS/Linux/Ubuntu) to obtain the output major.
Flask-SQLAlchemy is an extension for Flask that adds support for SQLAlchemy to your application. It aims to simplify using SQLAlchemy with Flask by providing useful defaults and extra helpers that make it easier to accomplish common tasks.
SQLAlchemy is a library that facilitates the communication between Python programs and databases. Most of the times, this library is used as an Object Relational Mapper (ORM) tool that translates Python classes to tables on relational databases and automatically converts function calls to SQL statements.
