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']}, ...
本文除了会详细分析 PEP-275 和 PEP-3103,还会介绍到 Python 最新的发展动态(PEP-622),即可能要引入的模式匹配(pattern matching)语法,相信这个话题会开阔大家的眼界,从而对 switch 语法有更为全面的认识。 1、switch 是什么? 在开始正题之前,我们需要先聊聊 switch 是什么?
在Python 3.10及更高版本中，`match-case` 结构模式匹配允许你根据变量的值与一系列模式进行比较。尽管...
