Blynk MQTT client for Python 3

Python 3, with its extensive library ecosystem and ease of use, is a popular choice for developing IoT Edge and Embedded Systems, particularly for prototyping and scripting applications. It supports rapid development cycles due to its high-level syntax and dynamic typing. Python is often used in IoT devices for data analysis, web server implementation, and interfacing with hardware components.

Its versatility makes it suitable for a wide range of IoT applications, from simple sensor data collection to complex data processing and IoT gateway services.
