Day 7 & 8: Python Full Stack Development

Kalainithi sekar — Wed, 26 Aug 2026 15:20:11 +0000

Day 7 & 8 of learning Python Full Stack Development, yesterday and today I have started taking an notes for my project ideas and studying about API. As I'm going to started my project, reading some SRS, architecture and features involving in my project and side by side I was learning fastAPI

Day 6: Python Full Stack Development Learning

Kalainithi sekar — Sun, 23 Aug 2026 09:27:20 +0000

Today, its in-depth learning for API concept like working, uses and importants API. And now i can write an code for API in Python using FastAPI likely:
installing the fastAPI
"pip install fastapi uvicorn"
create a file called "main.py"

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def home():
return {"message": "Welcome to my first API"}

@app.get("/student")
def get_student():
return {
"id": 1,
"name": "Kavin",
"age": 21,
"department": "Computer Science"
}
to run this code, go to the folder containing "main.py" and similar to "Uvicorn running on http://" running , opening through browser and returns the message as "Welcome to my first API "
output:
{
"id": 1,
"name": "Kavin",
"age": 21,
"department": "Computer Science"
}

let's know what happened behind the code

At the end of this I could understand how could API can connect though the server.

Day 5: Python Full Stack Development

Day 5 of learning Python Full Stack Development
Today it start with API , In real world applications, API connect the frontend , backend, databases, mobile apps and external services. Starting with how to use an API - client /consumer and how to create an API -API developer/provider .It officially covers query parameter, validation, authentication-related features and testing.

The API receives the request, Python processes it, gets the data from the database and sends the response back. Real world example like weather application. And now I have understood, why do we need API's, Architecture Important like frontend to backend application and more.

Second concept In Python, routers and factories are design patterns and architectural tools used to organize code, manage control flow, and create objects efficiently. They are highly prevalent in web frameworks like FastAPI, Flask, and Django, as well as in general software development.

Combining Both: A Real-World Architecture In a professional Python application, routers and factories often work together. A Factory creates the application instance, and Routers are then attached to that instance to organize the endpoints.

Day 4:My Python Full Stack Development Learning Journey

Day 4 of learning Python Full Stack Development,
Today its starts with learning NLP concept like that helps computers understand, process, analyze and generate human language ,its important NLP and working process .Added on Natural Language Processing libraries like NLTK(Natural Language Toolkit),NLP libraries and application.

Second topic FastAPI , fast python web framework used to build APIs(Application Programming Interfaces), useful for backend technology and responding. HTTP Methods like GET, POST, DELETE and path , query parameters.
Frontend sends text to FastAPI → FastAPI processes it with an NLP/ML model → returns the prediction to the frontend.

added on some libraries in python like Pandas and SciPy are important libraries used in different platform like Data science ,ML etc,...

I'm excited learn further topics in upcoming sessions

learning, Practicing, and strengthening !

My Python Full Stack Development Learning Journey

Day 2 & 3: My Python Full Stack Development Learning Journey 🐍💻

My journey in **Python Full Stack Development continues! 🚀

During Day 2 and Day 3, I learned several important Python basics, including variables, data types, operators, conditional statements, and taking input from the user.

To strengthen my understanding, I practiced simple programs such as:

Checking whether a number is positive, negative, or zero
Checking whether a number is odd or even
Creating a simple calculator using if-else conditions
Working with different data types and user inputs

These practice programs helped me understand how Python works in real situations rather than just learning the concepts theoretically.

By the end of these sessions, I felt more confident and gained a stronger understanding of the concepts I practiced. I’m excited to continue learning, practicing, and improving my Python skills step by step.

Day 2 & 3 — Learning, Practicing, and Growing! 💪

From Today, I Started My Journey in Python Full Stack Development

Kalainithi sekar — Thu, 13 Aug 2026 12:33:13 +0000

Today, I started my journey in Python Full Stack Development.
It was my first class, and we began with a simple self-introduction.
My mentor then explained the basics of Python programming.
I practiced simple programs like addition, subtraction, and multiplication.
I also created a small program to display student information using variables.
I realized that strong basics are important for becoming a good developer.
This is just the beginning, and I am excited to learn more in the coming days.
Every expert was once a beginner.
Today, I started my journey.
