测试发现(test discovery):pytest不需要提供显式和明确的子类和命名规则(naming convention)就可以自动发现测试文件和测试用例;unittest遵循严格的发现机制 固定件(fixtures)和插件(fixtures&plugins):pytest提供了功能强大的fixture mechanism,简化了测试设定和teardown。fixture可用于定义重复使用的设定和code cleanup,提升测试...
This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Please see the companion informational PEP describing style guidelines for the C code in the C implementation of Python [1] . 本文提供的编码规范用于Python主发行版中的标准库的...
Python 中的naming convention 以及 coding standard 有很多好的实践,例如Google 的Python 编程规范等。 就命名规范而言, 可以参见Python之父Guido推荐的规范,见下表: 迭代器 迭代是数据处理的基础, 采用一种惰性获取数据的方式, 即按需一次获取一个数据,这就是迭代器模式. 迭代器是一个带状态的对象,检查一个对象...
Now you know what constants are, as well as why and when to use them in your code. You also know that Python doesn’t have strict constants. The Python community uses uppercase letters as a naming convention to communicate that a variable should be used as a constant. This naming convent...
