### We Make Mistakes { #we-make-mistakes }

We, as humans, make **mistakes**, all the time. Software almost *always* has **bugs** hidden in different places. 🐛

And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### エディタのサポート

すべてのフレームワークは使いやすく直感的に使用できるように設計されており、すべての決定は開発を開始する前でも複数のエディターでテストされ、最高の開発体験が保証されます。

前回のPython開発者調査では、<a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">最も使用されている機能が「オートコンプリート」であることが明らかになりました。</a>

**FastAPI** フレームワークは、この要求を満たすことを基本としています。オートコンプリートはどこでも機能します。

ドキュメントに戻る必要はほとんどありません。

* And many other things

## Conclusion { #conclusion }

If you read and understood all this, now **you know much more** about virtual environments than many developers out there. 🤓

    We don't expect this to be a problem in practice!

 *  **OkHttp has an experimental new API for tracking metrics.** The new
    `EventListener` API is designed to help developers monitor HTTP requests'
    size and duration. This feature is an unstable preview: the API is subject
    to change, and the implementation is incomplete. This is a big new API we
    are eager for feedback.

* **Rapide à coder** : Augmente la vitesse de développement des fonctionnalités d'environ 200 % à 300 %. *
* **Moins de bugs** : Réduit d'environ 40 % les erreurs induites par le développeur. *
* **Intuitif** : Excellente compatibilité avec les IDE. <abbr title="également connu sous le nom d'auto-complétion, autocomplétion, IntelliSense">Complétion</abbr> complète. Moins de temps passé à déboguer.

These kinds of changes are unavoidable and
[permitted by the Go 1 compatibility rules](/doc/go1compat).
Even so, Go provides a mechanism called GODEBUG to
reduce the impact such changes have on Go developers
using newer toolchains to compile old code.

A GODEBUG setting is a `key=value` pair
that controls the execution of certain parts of a Go program.
The environment variable `GODEBUG`

 * silently replaced with spaces? If a query parameter contains a '&', does that get escaped?
 * By offering methods to read and write individual query parameters directly, application
 * developers are saved from the hassles of encoding and decoding.

 * ### Plus a modern API

 * The URL (JDK1.0) and URI (Java 1.4) classes predate builders and instead use telescoping
