Я протестував кілька ідей у найпопулярніших Python-редакторах: PyCharm, VS Code, редакторах на основі Jedi.

За даними [Python Developer Survey](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools), це охоплює близько 80% користувачів.

I tested several ideas in the most popular Python editors: PyCharm, VS Code, Jedi based editors.

By the last [Python Developer Survey](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools), that covers about 80% of the users.

        assertEquals("first", DocumentUtil.getValue(doc, "key", String.class));

        List<String> numList = Arrays.asList("123", "456", "789");
        doc.put("numKey", numList);
        assertEquals(Integer.valueOf(123), DocumentUtil.getValue(doc, "numKey", Integer.class));
    }

    @Test
    public void test_first_element_from_string_array() {
        Map<String, Object> doc = new HashMap<>();

}

// Disable before debugging non-obvious errors from the type-checker.
const usePkgCache = true

var (
	pkgCache = map[string]*apiPackage{} // map tagKey to package
	pkgTags  = map[string][]string{}    // map import dir to list of relevant tags
)

// tagKey returns the tag-based key to use in the pkgCache.
// It is a comma-separated string; the first part is dir, the rest tags.

Çeşitli fikirleri en popüler Python editörlerinde test ettim: PyCharm, VS Code, Jedi tabanlı editörler.

Bu test, en son [Python Geliştirici Anketi](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools)'ine göre, kullanıcıların yaklaşık %80'inin kullandığı editörleri kapsıyor.

J'ai testé plusieurs idées dans les éditeurs Python les plus populaires : PyCharm, VS Code, les éditeurs basés sur Jedi.

D'après la dernière [Enquête Développeurs Python](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools), cela couvre environ 80% des utilisateurs.

## 设计 { #design }

然后，我又花了一些时间从用户角度（使用 FastAPI 的开发者）设计了开发者 **API**。

同时，我还在最流行的 Python 代码编辑器中测试了很多思路，包括 PyCharm、VS Code、基于 Jedi 的编辑器。

根据最新 [Python 开发者调研报告](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools)显示，这几种编辑器覆盖了约 80% 的用户。

也就是说，**FastAPI** 针对差不多 80% 的 Python 开发者使用的编辑器进行了测试，而且其它大多数编辑器的工作方式也与之类似，因此，**FastAPI** 的优势几乎能在所有编辑器上体现。

通过这种方式，我就能找到尽可能减少代码重复的最佳方式，进而实现处处都有自动补全、类型提示与错误检查等支持。
