There are many frameworks in python which allows you to create webpage like bottle, flask, django. In this article you will learn how to create simple app bottle.Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. It is distributed as a single file module and has no dependencies other than the Python Standard Library.

In order to create the app using bottle we have to install it first
Windows
pip install bottle
Ubuntu
pip3 install bottle
By default, if we pass a template name to the SimpleTemplate and it will look for a file by that name in a subdirectory views with the extension .tpl.
First we have to create the directory for our project Test_project
Inside that create a file and name it as app.py
app.py
Python3
from bottle import route, run, template @route('/') def index(): return template('index.tpl') run(host='localhost', port=8080,debug=True) |
Then create the new directory views
Inside that create a file index.tpl
HTML
<html> <head> <title>GFG</title> </head> <body> <h1>Welcome to GFG</h1> </body> </html> |
To run this app open cmd or terminal
Windows
python app.py
Ubuntu
python3 app.py
Output :
To handle POST method in bottle we have to write two functions one for GET method and one for POST method.
Python3
from bottle import get,post,request,Bottle,run,template app = Bottle() @app.get('/updateData') # For GET method def login_form(): return template('index.tpl') @app.post('/updateData') #For POST method def submit_form(): name = request.forms.get('name') print(name) return f'<h1>{name}</h1>' run(app, host='0.0.0.0', port=8000) |
Inside views directory create new file forms.tpl
HTML
<html> <head> <title>GFG</title> </head> <body> <form method="post" action="/updateData"> <input type="text" name="name"> <button type="submit">Save</button> </form> </body> </html> |
To run this app open cmd or terminal
