PyWebConnect - Building a Python Web Application

Objective: Create a Python web application that allows users to connect and interact with various APIs, showcasing both backend and frontend development skills.

Learning Outcomes:

  • Understanding of backend development using Python
  • Proficiency in frontend development for web applications
  • Integration of APIs into a web application
  • Deployment of a web application

Steps and Tasks:

1. Setting Up the Project Environment:

  • Create a new directory for the project
  • Set up a virtual environment for Python
  • Install necessary packages like Flask for backend and Bootstrap for frontend

Need a little extra help?

mkdir PyWebConnect
cd PyWebConnect
python -m venv venv
source venv/bin/activate
pip install Flask Flask-Cors requests

2. Designing the Backend:

  • Create a Flask application with routes for different functionalities
  • Implement API calls to fetch data from external sources
  • Handle data processing and manipulation on the server side

Need a little extra help?

from flask import Flask, jsonify
import requests

app = Flask(__name__)

def get_data():
    response = requests.get('')
    data = response.json()
    processed_data = process_data(data)
    return jsonify(processed_data)

def process_data(data):
    # Perform data processing here
    return processed_data

if __name__ == '__main__':

3. Creating the Frontend Interface:

  • Design a user-friendly interface using HTML, CSS, and Bootstrap
  • Use JavaScript to interact with the backend API endpoints asynchronously
  • Display the fetched data in a visually appealing manner on the frontend

Need a little extra help?

<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="">
    <div class="container">
        <div id="data"></div>
    <script src=""></script>
    <script src="app.js"></script>

4. Implementing Frontend Functionality:

  • Write JavaScript code to make AJAX calls to the backend API
  • Update the frontend dynamically with the fetched data
  • Handle user interactions and events on the frontend

Need a little extra help?

// app.js
$(document).ready(function() {
    $.get('/api/data', function(data) {
        // Update the frontend with the fetched data

5. Deployment and Testing:

  • Deploy the web application on a hosting platform like Heroku or PythonAnywhere
  • Test the application to ensure all functionalities work as expected
  • Make any necessary adjustments based on user feedback or testing results

Evaluation: The project will be evaluated based on:

  • Functionality of the backend API calls and data processing
  • User interface design and responsiveness
  • Integration of frontend and backend components
  • Successful deployment and testing of the web application

Resources and Learning Materials:
