Micro Python is a version of Python that runs on microcontrollers. It allows Python code to control microcontrollers like the STM32F4 Discovery board. The document discusses the Micro Python project, the pyboard development board, and demonstrates some example Python code for controlling LEDs, reading switches, and using other hardware on the STM32F4 Discovery board with Micro Python.
The document discusses TypeScript and AngularJS concepts like classes, interfaces, dependency injection, and RESTful APIs. It provides examples of defining AngularJS controllers and services in TypeScript using classes, interfaces for type safety, and dependency injection. It also shows how to create a RESTful resource class in TypeScript to abstract HTTP requests.
This document discusses SQLAlchemy, a Python library for accessing relational databases. It provides an object-relational mapper (ORM) that allows Python objects to be mapped to database tables. Key features discussed include SQL expression, which allows SQL queries to be constructed programmatically in Python, and the unit of work pattern, where the ORM session tracks object states and generates SQL statements. The document also covers getting started with SQLAlchemy, including installing it, defining models, connecting to a database, querying models, and using sessions and transactions.
