二、什么是First-Class Functions 2.1 函数 是 对象 2.2 函数 可以被存储在数据结构中 2.3 函数 可以作为 参数 被传入其他的 函数 2.4 函数 可以被 嵌套 2.5 函数 可以 Capture Local State 2.6 对象 也可以变得像 函数 图书推荐 这篇文章在写作时,"function" 和"函数"两个名词会有混用的情况
1. First-class对象的定义 2. 函数基本定义 3. 将函数当作对象 4. 高阶函数(Higher-Order Functions) 5. 匿名函数(Anonymous Functions) 6. 可调用对象(Callable Objects) 7. 位置(Positional)参数、关键词(Keyword-only)参数 8. 函数式编程 参考:Ramalho, L. (2015). Fluent python: Clear, concise, and...
Python’s functions are first-class objects. You can assign them to variables, store them in data structures, pass them as arguments to other functions, and even return them as values from other functions. Grokking these concepts intuitively will make understanding advanced features in Python likel...

First-Class ObjectsIn functional programming, you work almost entirely with pure functions that don’t have side effects. While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This...
最后,为了提灵活性,我们允许构造嵌套远程函数(nested remote functions),意味着在一个远程函数内可以调用另一个远程函数。这对于获得高扩展性是至关重要的,因为它允许多个进程以分布式的方式相互调用(这一点是很强大的,通过合理设计函数,可以使得可以并行部分都变成远程函数,从而提高并行性)。
