刚开始学python的时候看到那些@app.get('/')这样的写法总觉得好高级,但真正接触后发现原来只是一种嵌套函数的简化写法,于是就怯魅了.

题外话:一开始翻了翻中文互联网,查不到一点有用的东西,一怒之下搜索在搜索结果里屏蔽某些网站的方法,找到了ublacklist,瞬间清爽了

定义
In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express.
It makes the language “sweeter” for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.

  • 尽管意思很明了,但这个名字确实很奇怪

总而言之,语法糖就是用简单的写法来取代复杂难懂的原生写法,实现的功能并不变,但读起来简洁很多

python中最有名的语法糖自然就是’@decorator’这样的了
