Choosing a Framework

When coding a website in Python, selecting the right framework is crucial as it provides the structure and tools necessary for development. The most popular frameworks include Flask and Django.

Flask is a micro-framework that is lightweight and modular, making it an excellent choice for small to medium-sized applications. Its simplicity allows developers to add only the components they need.

Django, on the other hand, is a high-level framework that follows the “batteries included” philosophy, providing numerous features out of the box, such as an ORM (Object-Relational Mapping), authentication, and an admin interface. This makes it ideal for larger projects that require scalability and security.

Feature Flask Django
Type Micro-framework Full-stack framework
Flexibility Very High Moderate
Built-in Tools Limited Extensive
Learning Curve Easy Moderate

Setting Up the Development Environment

After selecting a framework, the next step is to set up the development environment. This typically involves the following steps:

  • Install Python: Ensure that Python is installed on your machine. You can download it from the official Python website.
  • Create a Virtual Environment: Using `venv` or `virtualenv`, create a virtual environment to manage dependencies.

“`bash
python -m venv myenv
source myenv/bin/activate On Windows use: myenv\Scripts\activate
“`

  • Install Framework: Use `pip` to install your chosen framework. For instance, to install Flask or Django, you would run:

“`bash
pip install Flask
or
pip install Django
“`

Creating a Simple Web Application

To illustrate how to code a website in Python, here’s a brief example of creating a simple web application using Flask.

  1. Create the Application File: Start by creating a file named `app.py`.

“`python
from flask import Flask

app = Flask(__name__)

@app.route(‘/’)
def home():
return “Welcome to My Website!”

if __name__ == ‘__main__’:
app.run(debug=True)
“`

  1. Run the Application: Execute the application by running:

“`bash
python app.py
“`

  1. Access the Web Application: Open your web browser and navigate to `http://127.0.0.1:5000/` to see your website in action.

Adding Templates and Static Files

Enhancing your web application with templates and static files is essential for creating a user-friendly interface. Flask uses Jinja2 as its templating engine, allowing you to create HTML templates that can include dynamic content.

  • Create a Templates Folder: Inside your project directory, create a folder named `templates`.
  • Create an HTML File: Inside the `templates` folder, create a file named `index.html`.

“`html




My Website

Welcome to My Website!



“`

  • Render the Template in the Application: Modify your `app.py` to render the template:

“`python
from flask import render_template

@app.route(‘/’)
def home():
return render_template(‘index.html’)
“`

Static files such as CSS or JavaScript should be placed in a folder named `static`, which Flask will serve automatically.

By following these steps, you can establish a solid foundation for coding a website in Python, allowing for further enhancement and expansion of your application.

Choosing the Right Framework

When coding a website in Python, selecting the appropriate web framework is crucial. Each framework has its strengths and is suited for different types of projects. The most popular Python web frameworks include:

  • Django: A high-level framework that encourages rapid development and clean, pragmatic design. Ideal for complex, data-driven websites.
  • Flask: A micro-framework that is lightweight and modular. It is suitable for simpler applications where flexibility is a priority.
  • FastAPI: Known for its speed and support for asynchronous programming. Best for building APIs quickly and efficiently.
Framework Strengths Best Use Cases
Django Feature-rich, secure E-commerce, content management
Flask Lightweight, flexible Prototyping, small applications
FastAPI Performance, async support RESTful APIs, microservices

Setting Up Your Development Environment

To begin coding a website in Python, set up your development environment properly. Follow these steps:

  1. Install Python: Ensure you have Python installed on your machine. You can download it from the [official Python website](https://www.python.org/downloads/).
  2. Choose a Code Editor: Popular editors include Visual Studio Code, PyCharm, or Sublime Text.
  3. Set Up a Virtual Environment:
  • Use `venv` or `virtualenv` to create isolated environments for your projects.
  • Command: `python -m venv myprojectenv`
  1. Install Required Packages: Use `pip` to install the chosen framework.
  • For Django: `pip install django`
  • For Flask: `pip install flask`
  • For FastAPI: `pip install fastapi uvicorn`

Creating Your First Web Application

Regardless of the framework chosen, the process of creating a basic web application is fairly similar. Here’s a quick guide for each framework:

Django:

  • Create a new project:

“`bash
django-admin startproject myproject
“`

  • Run the development server:

“`bash
python manage.py runserver
“`

Flask:

  • Create a new file, `app.py`, and add the following code:

“`python
from flask import Flask
app = Flask(__name__)

@app.route(‘/’)
def home():
return “Hello, World!”

if __name__ == ‘__main__’:
app.run(debug=True)
“`

  • Run the application:

“`bash
python app.py
“`

FastAPI:

  • Create a new file, `main.py`, and add:

“`python
from fastapi import FastAPI
app = FastAPI()

@app.get(“/”)
def read_root():
return {“Hello”: “World”}
“`

  • Run the application:

“`bash
uvicorn main:app –reload
“`

Routing and Handling Requests

Routing is essential for managing URLs and directing requests to the appropriate functions. Each framework has its own way of handling this.

  • Django: Define URLs in `urls.py`:

“`python
from django.urls import path
from .views import home

urlpatterns = [
path(”, home, name=’home’),
]
“`

  • Flask: Use decorators to define routes directly in your application code:

“`python
@app.route(‘/about’)
def about():
return “About Page”
“`

  • FastAPI: Use Python function annotations to define routes:

“`python
@app.get(“/items/{item_id}”)
def read_item(item_id: int):
return {“item_id”: item_id}
“`

Database Integration

Integrating a database is vital for dynamic applications. Common choices include SQLite, PostgreSQL, and MySQL. Here’s a brief overview of how to connect to a database in each framework:

  • Django: Django comes with an ORM and supports various databases. Configure your database settings in `settings.py`.
  • Flask: Use SQLAlchemy or Flask-SQLAlchemy for ORM support. Example configuration:

“`python
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy(app)
“`

  • FastAPI: Use SQLAlchemy or databases for async support. An example connection might look like:

“`python
from sqlalchemy import create_engine
engine = create_engine(“sqlite:///./test.db”)
“`

These frameworks provide extensive documentation and communities that can support you as you build your website.

I’m Leonard a developer by trade, a problem solver by nature, and the person behind every line and post on Freak Learn.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
