To give a demo that i have posted before,install is
pip install Flask
.This is all you need for local development(Flask has build in web server),forget about WAMP,LAMP or XAMPP as you may have used in PHP.
Setup folder/files:
my_app |-- app.py templates\ |-- index.html |-- about.html static\ css\ |-- style.css js\ img\app.py:
from flask import Flask, render_template, jsonify, request app = Flask(__name__) @app.route('/') def index(): return render_template("index.html") @app.route('/about', methods=['GET']) def about(): return render_template("about.html") if __name__ == '__main__': app.run(debug=True)index.html:
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>Some title</title> <link rel=stylesheet type=text/css href="{{ url_for('static', filename='css/style.css') }}" /> </head> <body> <div id="start"> <h1>Start page</h1> <ul> <li class="page_1"><a href="/about">About</a></li> </ul> </div> </body> </html>about.html:
<div class="foo"> <h1>The About Page</h1> <a href="https://python-forum.io/">Python forum</a> </div>style.css:
body { background: #67B26F; background: -webkit-linear-gradient(to right, #4ca2cd, #67B26F); background: linear-gradient(to right, #4ca2cd, #67B26F); font-size: 100%; padding:0; margin:0; } html { height: 100% }Now from command line in folder where
app.py
is.Run
python app.py
.Then it look like this:
E:\all_flask\my_app λ python app.py * Serving Flask app "app" (lazy loading) * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: on * Restarting with stat * Debugger is active! * Debugger PIN: 334-187-997 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)See address copy that to browser
http://127.0.0.1:5000/
.Then should show the page and with a link to about page.
So can to all development local to a finish web-app.
Only if want to share with world look for a Python friendly host eg DigitalOcean.
Now leave the local web-server and switch to a production ready web-server like Gunicorn.
