First Python / Flask Application

- 1 min

I like the quick draft section of WP - I’ll start using this to keep my posts short :).

Haven’t posted in a while, but here’s where I’m at - I now have two apps, written in Swift, on the Apple App Store. Both could use a lot of work, but I took a break to check out Python. As of this moment, I’m not opinionated on the religious “Down with PHP” conversations, but I definitely like Python a lot so far. It feels a bit quicker, has a LOT of easy libraries to import and seems to be more popular. Once I knocked out my first Python project, I was excited to start working with Python/Flask, because I’ll be honest: Ruby on Rails came off as overwhelming initially. Python/Flask felt like a perfect start.

Look at how easy it is to set up your Python/Flask application:


from flask import Flask

app = Flask(__name__)
app.debug = True

def hello():
    return "Hello, world!"

And there you have it! By installing your dependencies ahead of time (by executing pip install flask), you can paste this into a file called, run python, visit localhost:5000 and see “Hello, world!” in your browser (or via cURL request).

And adding a new route:

def new():
    return "Here is my new route!"

Not too bad! With a few simple lines, you can set up your first Python application!
