完成后,Python 3.10.0a6 就已经安装到系统中,直接命令行输入 python3.10 回车即可进入解释器。 语法 Pattern Matching 的全称是 Structural Pattern Matching(以下简称 SPM),中文可以翻为「结构模式匹配」,先搁置 Structural,先看后面的 pattern matching。 基础语法 代码语言:javascript 代码运行次数:0 运行 AI代码解...
简介:python结构化模式匹配switch-case,Python 3.10中引入,Python的模式匹配(pattern matching)语法 增加了采用模式加上相应动作的match 语句和case 语句的形式的结构化模式匹配。 模式由序列、映射、基本数据类型以及类实例构成。 模式匹配使得程序能够从复杂的数据类型中提取信息、根据数据结构实现分支,并基于不同的数据...
Python pattern match maps In the next example, we do pattern matching with maps. maps.py #!/usr/bin/python users = [ {'name': 'Paul', 'cols': ['red', 'blue', 'salmon']}, {'name': 'Martin', 'cols': ['blue']}, {'name': 'Lucia', 'cols': ['pink', 'brown']}, ...

Python, I love you. But I’d like you to change. It’s not you, it’s me. Really. See, you don’t have pattern matching. But, that’s not the root of it. Macros are the root of it. You don’t have macros but that’s OK. Right now, I want pattern matching. I know you...
PEPs 634, 635, and 636 have plenty of information on what structural pattern matching is bringing to Python, how to use it, the rationale for adding it to Python, etc. In this article I will try to focus on using this new feature to write beautiful code....
