Introduction to Web Development (Flask/Django)
What is Web Development
Web development involves creating websites and web applications that run in a browser.
Frontend vs Backend
- Frontend: User interface (HTML, CSS, JavaScript)
- Backend: Server-side logic (Python, databases)
Flask
- Lightweight framework
- Easy to learn for beginners
- Suitable for small to medium applications
Django
- Full-featured framework
- Built-in tools (authentication, admin panel)
- Suitable for large-scale applications
Example (Flask App)
from flask import Flaskapp = Flask(__name__)@app.route("/")
def home():
return "Hello World"app.run()- Introduction to Data Science
What is Data Science
Data science involves extracting insights from data using analysis, statistics, and visualization.
Role of Python
Python is widely used due to its simplicity and powerful libraries.
Workflow
- Collect data
- Clean data
- Analyze data
- Visualize results
Example
import pandas as pddata = {"Name": ["A", "B"], "Marks": [80, 90]}
df = pd.DataFrame(data)print(df.describe())Career Opportunities
