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.

• 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.

8. Command Prompt
TO TRY:
With the command line open, type in the
following command and press Enter:
Windows Command Prompt
C:> python --version
Python 3.8.4
Python Releases for Windows | Python.org

9. Alternative
Command
TO TRY:
Using the --version switch will show you the version that’s
installed. Alternatively, you can use the -V switch:
Windows Command Prompt
C:> python -V
Python 3.8.4 (3.12.4 is the one which I have installed)
Note: If you don’t have a version of Python on your system,
then both of the above commands will launch the Microsoft
Store and redirect you to the Python application page. You’ll
see how to complete the installation from the Microsoft Store in
the next section.

10. Ways to install
TO TRY: Check which version of
Python, if any, is
installed on your
machine
Install or update Python
on Windows, macOS,
and Linux
Use Python on mobile
devices like phones or
tablets
Use Python on the Web
with online interpreters

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
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
To call a function, use the function
name followed by parenthesis:
TO TRY:
def my_function():
print("Hello from a function")
my_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:
• 0
• 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:

29. 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:
•

30. 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:

31. 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:
