这篇文章在写作时,"function" 和"函数"两个名词会有混用的情况,主要是一些情况会更加通顺。 一、简介 这篇笔记是在我看 Dan Bader 的《Python Tricks: A Buffet of Awesome Python Features》时写下的,主要是理解 Decorators 之前要先懂 First-Class Functions。
Function in python are first-class objects (runtime / element / argument / return) 1. Treating a Function Like an Object 2. Higher-Order Fun
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...
正确理解 Python函数,能够帮助我们更好地理解 Python 装饰器、匿名函数(lambda)、函数式编程等高阶技术。 函数(Function)作为程序语言中不可或缺的一部分,太稀松平常了。但函数作为第一类对象(First-Class Object)却是 Python 函数的一大特性。那到底什么是第一类对象呢? 函数是对象 在Python 中万物皆为对象,函数也...

“function” to describe a reusable chunk of code. Other programming languages use names such as “procedure,”“subroutine,” and “method.” When a function is part of a Python class, it‘s known as a “method.”. You’ll learn all about Python’s classes and methods in a later ...

We call these dimensions first class because they are Python objects. In addition to the normal positional dimensions in a tensor, tensors can also have a separate set of first-class dimensions. You can create tensors with first-class dimensions by indexing the normal positional dimensions of a...
