it can happen that <code>g</code> prints <code>2</code> and then <code>0</code>.

**In this release MockWebServer has a new Maven coordinate and package name.** A longstanding
problem with MockWebServer has been its API dependency on JUnit 4. We've reorganized things to
remove that dependency while preserving backwards compatibility.

상대적으로 관계형 데이터베이스(예: MySQL 또는 PostgreSQL)와 강하게 결합되어 있어서, NoSQL 데이터베이스(예: Couchbase, MongoDB, Cassandra 등)를 주 저장 엔진으로 사용하는 것은 그리 쉽지 않습니다.

백엔드에서 HTML을 생성하기 위해 만들어졌지, 현대적인 프런트엔드(예: React, Vue.js, Angular)나 다른 시스템(예: <abbr title="Internet of Things - 사물 인터넷">IoT</abbr> 기기)에서 사용되는 API를 만들기 위해 설계된 것은 아닙니다.

它是最受歡迎且廣受信任的 Python 框架。像 Instagram 等系統就是用它打造的。

它與關聯式資料庫（如 MySQL 或 PostgreSQL）相對緊密耦合，因此要以 NoSQL 資料庫（如 Couchbase、MongoDB、Cassandra 等）作為主要儲存引擎並不容易。

它一開始是為在後端產生 HTML 而設計，而非為了建立提供現代前端（如 React、Vue.js、Angular）或其他系統（如 <abbr title="Internet of Things - 物聯網">IoT</abbr> 裝置）使用的 API。

Django REST framework 的目標是成為一套在 Django 之上構建 Web API 的彈性工具組，以強化其 API 能力。

Multi-threaded tests are often not reproducible due to the fact that there is
no guarantee on the order in which operations occur across threads. Adding
randomization to the mix usually makes things worse and should be done with
care.
