This repository contains simple Flask examples demonstrating basic routing, string manipulation, number checking, and HTML template rendering for eligibility checking.

• Root route (/) → returns Hello, World!
• Reverse string route (/reverse/<string:text>) → returns original and reversed string
• Armstrong number checker (/check/<int:num>) → checks if a number is an Armstrong number

# Navigate into repo
cd Flask  

# Install dependencies
pip install flask  

# Run Day 1 app
python first.py

App runs on: http://127.0.0.1:5000

• Learned how to use Flask’s render_template() to connect Python with HTML
• Introduced Jinja2 templating to dynamically display variables ({{ age }}) in HTML
• Applied separation of logic and presentation (Python logic in .py, UI in .html)
• Understood conditional rendering (eligible vs not eligible)

• Root route (/) → simple welcome message
• Age route (/age/<int:age>) → checks if a person is eligible or not eligible
• Uses Jinja2 templates (eligible.html and noteligible.html) for styled output

# Navigate into repo
cd Flask  

# Run Day 2 app
python app.py

App runs on: http://127.0.0.1:5000

• Both apps run in debug mode (debug=True) for auto-reload and detailed error messages.
• Day 1 demonstrates basic routing & string/number logic.
• Day 2 introduces Flask template rendering (HTML with Jinja2 variables).
