Introduction
Flask is micro-framework which has very little dependency on external libraries. It is a very light framework and gives us freedom to do whatever we want.
In this chapter, we are going to build a project using Python and Flask framework.
Flask Startup and Configuration
Like most widely used python libraries, the Flask package is installable from the Python Package Index (PPI). Let’s create a directory first (In this chapter, we have created a directory called flask project) then created a virtual environment (and called it flaskEnv) where all the project related dependencies will be loaded (including flask). You can also install flask-sqlalchemy so that your flask application has a simple way to communicate with the SQL database.
After installing the flask, your flaskEnv (our virtualEnvironment name) will show something like below −
Creating an app with flask
By installing flask, we can create a simple “hello application in flask” with very few lines of code as follows −
Type the following in the terminal −
$python flaskapp.py
And you can see the following output −
Running on http://127.0.0.1:5000/ or on localhost:5000
Below is the explanation of what we did in our example code −
- Firstly, we import the Flask class library. An instance from this class is the WSGI app.

- Secondly, we create an instance of this class. Application package or module name is our first argument. It is mandatory that flask knows where to find static files, templates and other files.

- Next is the route() decorator we use to know which URL should trigger our method/function.

Creating URL Routing
/hello
/members
/members/name
We can write the following code based on the above URL and save it as app.py.
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def index():
return "Index!"
@app.route('/Hello')
def hello():
return "Hello, World!"
@app.route("/members")
def members():
return "Members"
@app.route("/members//")
def getMember(name):
return name
if __name__ == '__main__':
app.run(debug=True)Liked what you read? Then don’t break the spree. Visit our insideAIML blog page to read more awesome articles.
