Python 3.10 has the match case which is Structural Pattern Matching. I'm going to show you what it can do with examples!
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...
Pattern matching is done withmatch/casekeywords. It was introduced in Python 3.10 under the namestructural pattern matching. Pattern matching is a powerful control flow construct that allows us to compare a value against a series of patterns and then execute code based on which pattern matches. I...
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...
Well, even for Python 3.10 they shouldn't be highlighted directly as keywords in general, but only if it is really the pattern matching statement. For example match = 42 is still a normal variable identifier, or re.match() would be a function call. I meant the backwards compatibility more...
With Python 3.10 developers will be able to useMATCH CASEstatements within their programs. One of the enhancements that is new in Python 3.10 is the announcement of structural pattern matching with Match Case statements. Up to 3.10 Python did not have aswitchor acasestatement. Although programmers...
It is more similar to pattern matching in languages like Rust or Haskell than a switch statement in C or C++.SyntaxThe following is the syntax of match-case statement in Python -match variable_name: case 'pattern 1' : statement 1 case 'pattern 2' : statement 2 ... case 'pattern n' ...
Python 3.10里面的Match-Case语法详解 前言 很多Python 核心开发者都认为 Python 不需要添加switch-case这种语法,因为可以通过if/elif/else实现一样的效果。事实上 Guido 本人也对这种语法不感冒,所以直到 Python 3.10 一个新的match-case才被加了进来。 这个新的语法中文叫做结构模式匹配 (Structural Pattern Matching...
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?
