長い間、Flaskアプリケーションの有名な「Hello, World」というサンプルコードは、7行構成でした。以下は、2017年6月12日のFlask Webサイトのスナップショットです。

その後、このサンプルアプリケーションは5行に短縮されました。以下は2017年6月17日の同じページです。

ご覧のように、アプリケーションのコア部分は変更ありませんが、アプリケーションサーバーの開始方法が大幅に変更されています。以前のサンプルでは、アプリケーションスクリプト内で単純なapp.run()コールを使用していますが、新しいサンプルではflask runコマンドとFLASK_APP環境変数を使用しています。

その後の数年間でFlask Webサイトのデザインは大きく変わりましたが、この記事を執筆している2020年の段階では、flask runメソッドはフレームワークの公式ドキュメントで最も頻繁に目にします。

現在も、多くのアプリケーションやコードチュートリアルでapp.run()メソッドが使用されています。理由の1つは、Flaskでは古くとも重要なコンテンツが数多く存在しているためです。app.run()が今も便利で使いやすいコマンドとして、広く利用されていることもあります。

この記事では、それぞれのメソッドの長所と短所について解説します。では、本題に入りましょう。

「app.run()」と「flask run」のどちらを使用するべきか？

Ah, la magie des chatbots... Ces produits remarquables permettant aux individus de créer de nouvelles expériences, allant de l'envoi d'actualités personnalisées à la diffusion d'informations sur les soins de santé destinés aux femmes. La première fois que j'ai entendu parler des bots, je n'imaginais pas que je serais un jour capable d'en créer un moi-même. Cela étant, je me suis vite plongé dans la documentation de Facebook Messenger et j'ai commencé à apprendre comment faire fonctionner un bot en un rien de temps, avec un peu de Python 3 et de Flask.

Dans cet article, nous aborderons les bots en allant des notions de base sur leur fonctionnement jusqu'à la construction de notre propre bot Facebook Messenger basique. Nous allons plus précisément construire une version de base de Black Girl Magic Bot, un bot Facebook Messenger qui envoie aux utilisatrices des images, des listes de lecture, et …

Every 17 years in the Eastern United States, billions of cicadas belonging to a brood called Brood X emerge from their underground burrows. Their last emergence was in 2004, and now in 2021 they are out and about once again.

A lot has changed over the last 17 years for these cicadas to catch up on, including massive updates to the Python programming language. Let's take a look at Python 2.3.4, the version of Python released in May 2004, and see how it differs from how we write Python today to put things in perspective for our buggy friends.

from may_2004 import newest_python_version

Releases for old Python versions are all still available on python.org, including Python 2.3.4, the that the Brood X Cicadas are most familiar with.

On this release archives page there are two tarball source release files, as well as a Windows installer. You can compile these …

Do you use Twilio Programmable Video for your video meetings? One of the many optional features is to enable recording of your video rooms.

Error detection is a key part of any application deployed in the cloud. No matter how much care we give to testing and software quality, there will always be factors - sometimes outside our control - that can make our applications fail.

In this article, we will build a native Python solution that extends the standard logging library to send application failure alerts through Twilio Programmable SMS and/or SendGrid Email APIs.

Requirements

We will be using Python 3.9, but any version of Python from 3.6 should work as well. You can download Python from the official python.org website.

Since our code will use Twilio and SendGrid services to dispatch error alerts, you will need an account in at least one of these services (ideally both). We provide instructions below on how to sign-up or log-in and also collect the data you will need from each account.
