Using Python if statement in Cases In Python, we can also use theifstatement in the case clauses. This is calledguard, which adds an additional condition to an expression. If the guard condition (theifstatement) evaluates toFalse, thematchstatement skips that case and continues to the next ...
Python3.10.0正式版本在月初终于发布了,其中一个重要的特性就是支持match-case语句,这一类似C语言switch-case语句终于在Python中实现了。 一般匹配模式 C语言中一个典型的swicht-case语句像下面这样,在switch里包含要判断的变量x,case语句后则是匹配变量值是多少,如果满足这个匹配条件,就执行“case n:”后面的语句,...
The Python programming language is under constant development, with new features and functionality added with every update. Python 3.10 was released in mid-2021 and comes with structural pattern matching, also known as amatch casestatement. This is Python 3.10’s most important new feature; the ne...

statement(s) subject是要进行匹配的值。 pattern是各种匹配模式,Python 会依次将subject与每个pattern进行匹配。如果匹配成功,则执行对应的代码块,并跳过后续的匹配。 _是通配符模式,表示匹配任何值,通常作为最后一个case子句,用于处理前面模式都不匹配的情况。

包括字典映射、函数组合和Python 3.10中引入的match-case语句。
A match statement takes an expression and compares its value to successive patterns given as one or more case blocks. This is superficially similar to a switch statement in C, Java or JavaScript (and many other languages), but it can also extract components (sequence elements or...
y = 1 match foo: case Foo(x=x): print(f"{x=}") case Foo(y=y): print(f"{y=}") with nuitka --standalone on Linux, or with nuitka --standalone --mingw64 on Windows, the resulting executable immediately crashes due to a segmentation fault. Environment > python -m nuitka --...
This PR adds the basic comparisons which can be found in python's match statement. The statement is modeled as a SwitchStatement and the main issue are the CaseStatements which offer a wide range o...
