1. Python Programming IoT Centre of Excellence Dr. Akey Sungheetha, Associate Professor, Computer Science and Engineering.

2. Python Programming Language The high-level language is a type of programming language designed to simplify computer programming. Memory-safe languages let programmers focus on quality code, avoiding risks of low-level memory management. Programming language expertise is essential in the rapidly changing field of computer engineering. White House urges developers to avoid C and C++, use 'memory-safe' programming languages  The NSA list of memory safe programming languages has been updated to reflect v1.1 of the information sheet.

3. Python Programming Uses Turbocharged Python: AI Accelerates Computing Speed by Thousands of Times Their development Scalene, an open-source tool for dramatically speeding up the programming language Python, circumvents hardware issues

4. Latest in Python Enhancing Llama2's Proficiency in Python through Supervised Fine-Tuning and Low-Rank Adaptation Techniques. From Python to C++, these are the top robotic programming languages bringing form and function to robots working in the world today.

5. How to Install Python on Windows There are three installation methods on Windows: The Microsoft Store The full installer Windows Subsystem for Linux

6. How to Check Your Python Version on Windows To check if you already have Python on your Windows machine, first open a command-line application, such as PowerShell. How to Check Your Python Version on Windows To check if you already have Python on your Windows machine, first open a command-line application, such as PowerShell.

7. Tip: Here’s how you open PowerShell: TO TRY: Press the Win key. Type PowerShell. Press Enter. Alternatively, you can right-click the Start button and select Windows PowerShell or Windows PowerShell (Admin). You can also use cmd.exe or Windows Terminal.

11. Online compilers Online Python Compiler (Interpreter) (programiz.com) Online Python Compiler - online editor (onlinegdb.com) Online Python - IDE, Editor, Compiler, Interpreter (online-python.com)

12. Write hello world program TO TRY: PY4E - Python for Everybody  IDE from coursera may be used. The print() function in Python is used to print Python objects as strings as standard output. print("Hello World")

13. Variables TO TRY: This Python code creates a variable message and assigns it the value “Hello, World!“. Then, the print() function is used to print the value of the message variable to the console. message = "Hello, World!" print(message) 

14. Expressions in Python TO TRY: An expression is a combination of operators and operands that is interpreted to produce some other value.  In any programming language, an expression is evaluated as per the precedence of its operators.  So that if there is more than one operator in an expression, their precedence decides which operation will be performed first. x = 15 + 1.3 print(x)

15. Python Conditions and If statements Python supports the usual logical conditions from mathematics: Equals: a == b Not Equals: a != b Less than: a < b Less than or equal to: a <= b Greater than: a > b Greater than or equal to: a >= b

16. Python Conditions and If statements TO TRY: a = 33 b = 200 if b > a:   print("b is greater than a") Note: Tab space preceding print is necessary

17. Creating a Function A function is a block of code which only runs when it is called. In Python a function is defined using the defkeyword: TO TRY: def my_function():     print("Hello from a function")

18. Calling a Function

19. Loops in Python Python programming language provides two types of loops – For loop and While loop to handle looping requirements.  TO TRY: count = 0 while (count < 3):     count = count + 1 print("Hello friends")

20. While loop and For Loop in Python A while loop is used to execute a block of statements repeatedly until a given condition is satisfied. When the condition becomes false, the line immediately after the loop in the program is executed. For loops are used for sequential traversal. For example: traversing a list or string or array etc. In Python, there is “for in” loop which is like foreach loop in other languages.

21. For loop example n = 4 for i in range(0, n):     print( i ) Output: 1 2 3

25. NUMPY Numpy is a scientific computing package that helps to create datasets to test with the time series data in IoT. Numpy features are used in IoT to read sensor bulk data from the database inbuilt functions in the system SOCKETS AND MYSQLDB Sockets that facilitate networking in IoT devices include TCP/IP and UDP, which are compatible to work with Python packages. TCP/IP and UDP act as transport layer protocols for communication. The MySQLdb is a go-to relational format database that helps in the development of remote stores for the IoT system.

26. MATPLOTLIB To get data insights, matplotlib visualizes the most paramount operations by giving a variety of graphs to represent the data. REQUESTS, TKINTER AND TENSORFLOW To make HTTP calls and parse responses in Python, the request package acts as a major protocol for data exchanges. Tkinter GUI puts the aspects of Python script in a controlled distribution, which enables functional testing and repeated executions in IoT Python devices. Therefore, the numerical computations of machine learning initiated into the IoT systems utilize the representation in data flow graphs dealing with huge non-linear datasets and deep learning aspects.

27. IOT DEVICES USED TO DEVELOP APPLICATIONS IN IOT Raspberry Pi Model 3 Intel Edison Arduino IOT SENSORS SIMULATORS USED IN PYTHON PROGRAMMING INCLUDE: MQ TELEMETRY TRANSPORT (MQTT) SENSOR SIMULATOR MQTT protocol for the IoT in Python enables high-speed data exchange with low payload communication between the devices. User-friendly requests of MQTT are made directly in Python. Data is collected in real-time and easily analyzed in mathematical computation libraries like matplotlib. The diagram below shows the steps used for the data flow:

28. https://www.topcoder.com/thrive/articles/python-in-iot-internet-of-things Data logging using MQTT (install using  pip install paho-mqtt ) Python is displayed below: import paho.mqtt.client as mqtt #Callback for received data from server def on_connect(data_iot, user, events): print(“connected with code” + str(events)) data = mqtt.Client() Data.on_connect = on_connect Data.on_message = on_message data.loop_forever() For instance, the MQTT protocol is used to send data of a light bulb and install required dependencies and libraries as indicated below:  

29. AZURE IOT SDK IN PYTHON Azure IoT hub offers a variety of features for IoT SDK usage which provides the ability to connect devices and services. The IoT SDK is supported by the MQTT protocol which facilitates the data exchange processes. The device requirements to be used along with Python include: Python version 3.7+: helps in both asynchronous and synchronous API Azure-iot-device library The IoT hub SDK helps with the following aspects: access, processing, and analysis of data for machine learning applications. The Azure IoT hub helps collect messages and feedback data collected by IoT devices and is displayed in the code below:

30. COUNTLY IOT RASPBERRY PI SDK Sending data and visualizing data on a dashboard is simplified by involving the Countly IoT Pi SDK, which relies on internet connectivity for efficient and effective data insights from the device. The code below is used to start the process of collecting data using Countly IoT Pi SDK in Python. Install by running:  pip install Raspberry_SDK : from Raspberry_SDK.Countly import Countly #intiate the SDK Countly = Countly(“SERVER_URL”, “APP_KEY”, 0) #Send an event countly.event(“NAME”, VALUE) Countly SDK also helps to retrieve data events for both analog and digital circuits. Use case of Countly IoT Raspberry Pi SDK is applicable in  temperature room measuring  and  Bulb light . For instance, the server gets to pass the application key to collect the data and data is being manipulated by  GroveAPI  for raspberry IoT as displayed below:
