Python with GenAi and DevSecOps Training 2025 – Session 7

VGLUG is dedicated to empowering rural college students through technology education.
As part of this initiative, we conduct weekly training sessions on Python With GenAI and DevSecOps..

Due to the large number of participants, the training is organized into six teams:

• Python & GenAI –  Linus Torvalds(Team 1) &  Grace Hopper(Team 2): Assigned to Engineering students
• Python & GenAI –  Richard Stallman(Team 1) & Aron Swatz (Team 2): Assigned to Arts and Science students
• DevSecOps –  Ada Lovelace (Arts) & Bob Thomas (Engg): Comprising both Engineering and Arts students

These sessions focus on practical knowledge of Python, GenAI, DevSecOps, free and open-source tools, and also include social awareness and community engagement activities.

Python With GenAI – Richard Stallman and Aron Swatz(Arts) :

Session 1: Problem Solving Using Looping – Kowsalya & Dilip

This weekend’s VGLUG meetup focused on mastering looping concepts (for, while, and nested loops) by solving real-time problems using Python. Students were grouped into 9 teams and given 9 different logic-based tasks.

All teams successfully implemented and explained their logic. Two students confidently came forward to present their solutions to everyone, sharing how they approached the problem. They also answered questions from others, turning the session into an interactive peer-learning experience. It was a fun, hands-on day of coding, learning, and collaboration.

Session 2:

Wikisource – Kowsalya & Dilip

In the second session, students were introduced to Wikisource and guided to create their own user accounts on the platform. After account creation, the session continued with an explanation of how Wikisource works, its contribution flow, and how users can help digitize and proofread public domain books. The process of contributing Tamil literature was also demonstrated, and students got a clear understanding of how their small efforts can support open knowledge. The session created curiosity among many, and some even started exploring Tamil books on the spot.

Session 1: Keywords, Variables, Data Types – Kanimozhi & Deepak

What is a Keyword?

• Keywords are reserved words in Python that have special meaning.
• They are part of the Python language syntax and cannot be used as variable names.
• Python has 35+ keywords (as of Python 3.10), including:
• if, else, elif, for, while, break, continue, def, return, True, False, None, and, or, not, etc.

What is a Variable?

• A variable is a name given to a memory location to store data.
• In Python, you don’t need to declare the data type of a variable — it is automatically detected.

Example:

name = “VGLUG” # String
age = 18 # Integer
height = 5.8 # Float
is_active = True # Boolean

What is a Data Type?

• A data type defines the kind of value a variable holds.
• Python has several built-in data types.

Types of Data Types in Python:

1. Numeric Types

• int – Integer numbers (10, -5)
• float – Decimal numbers (3.14, -2.5)
• complex – Complex numbers (2 + 3j)

2. Text Type

• str – String (“Hello”, ‘VGLUG’)

3. Boolean Type

• bool – True or False

4. Sequence Types

• list – Ordered, changeable, allows duplicates
  my_list = [1, 2, 3]
• tuple – Ordered, unchangeable, allows duplicates
  my_tuple = (1, 2, 3)
• range – Sequence of numbers
  range(5) gives 0 to 4

5. Set Types

• set – Unordered, no duplicates
  my_set = {1, 2, 3}

6. Mapping Type

• dict – Key-value pairs
  my_dict = {"name": "VGLUG", "age": 18}

7. None Type

• None – Represents no value or empty
  x = None

Session 2: WordPress – Vasanth

What is WordPress?

• WordPress is a free and open-source Content Management System (CMS) used to build and manage websites without needing to write code.
• It was originally created for blogging but has grown into a platform for building all kinds of websites — blogs, e-commerce sites, portfolios, company websites, and more.

Why Learn WordPress?

• No coding knowledge required to build powerful websites
• Used by freelancers, NGOs, startups, and even governments
• Great for portfolio projects and community websites
• Perfect for non-technical students to contribute to open web

Session 1:Linux Advanced Commands – Vignesh

After learning basic Linux commands (like ls, cd, mkdir, rm, etc.), it’s important to explore more advanced Linux commands that help in managing processes, files, permissions, users, and networks. These are commonly used by developers, system admins, DevOps engineers, and power users.

Example commands:

File Permissions & Ownership

ls -l
chmod +x script.sh
chmod 755 file.txt
sudo chown user:group file.txt

Process Management

ps aux
top
kill -9
nice -n 10 command
renice -n 5

Archive & Compression

tar -cvf archive.tar folder/
tar -xvf archive.tar
gzip file.txt
gunzip file.txt.gz

Disk Usage & Space

df -h
du -sh folder/

Networking Commands

ip a
ping google.com
netstat -tuln

Package Management (Debian/Ubuntu)

sudo apt update
sudo apt upgrade
sudo apt install package-name
sudo apt remove package-name

File Searching

find / -name “*.pdf”
find . -mtime -1
grep “search_text” *.txt

User Management

sudo adduser username
sudo deluser username
su – username

Combine Commands

mkdir test && cd test
command1 || echo “Failed”
cd folder; ls; pwd

Bonus

history
alias ll=’ls -la’
crontab -e
man grep

Session 2: Git – Vijayalakshmi
What is Git?

🔹 Git is a version control system.
🔹 It helps developers track changes in their code and collaborate with others.
🔹 Git was created by Linus Torvalds (creator of Linux) in 2005.

Why Use Git?

Problem Without Git	Solution With Git
Accidentally deleting code	Git lets you go back to old version
Team members overwrite changes	Git lets everyone work together safely
Confusion over file versions	Git tracks every change and update

Basic Git Commands:

Command	Meaning
git init	Start a new Git project
git status	Check the current state
git add filename	Stage file changes
git commit -m "message"	Save the changes with a message
git log	View previous commits
git clone URL	Copy a remote project to local
git push	Upload your changes
git pull	Download latest changes from others

Git Workflow (Simple Steps)

git init → Start a project

git add → Stage the changes

git commit → Save the changes

git push → Send to GitHub or GitLab

Session 1:Operating System Fundamentals- Loganathan

What is an Operating System?

An Operating System (OS) is a system software that acts as an interface between the user and the computer hardware. It manages all the hardware, software, memory, processes, and input/output operations. Without an OS, a user cannot interact with the computer system.

Common examples: Windows, Linux, macOS, Android, iOS

Main Functions of an Operating System:

• Process Management
• Manages processes (running programs), including scheduling, creation, termination, and resource allocation.
• Memory Management
• Handles and allocates RAM to applications efficiently.
• File System Management
• Organizes data into files and directories and manages file access and permissions.
• Device Management
• Controls and coordinates the use of hardware devices (like keyboard, mouse, printer).
• User Interface
• Provides GUI (Graphical) or CLI (Command Line) for user interaction.
• Security and Access Control
• Protects system resources and manages user authentication and permissions.
• I/O System Management
• Manages input/output devices and handles data transfer between them and applications.

Types of User Interfaces:

• CLI (Command Line Interface): User interacts via text commands (e.g., Linux terminal)
• GUI (Graphical User Interface): User interacts via icons and windows (e.g., Windows, macOS)

Why Learn OS Fundamentals?

• Helps understand how software interacts with hardware
• Crucial for programming, system administration, and cybersecurity
• Forms the base for advanced topics like processes, scheduling, memory management, and OS internals

Examples of Operating Systems:

• Windows – User-friendly GUI, widely used on desktops.
• Linux – Open-source, powerful for programming and servers.
• macOS – Apple’s desktop OS, secure and smooth.
• Android – Most-used mobile OS, built on Linux kernel.
• iOS – Apple’s mobile OS, known for performance and security.
