The Python programming language does not have a built in switch/case control structure as found in many other high level programming languages. It is thought by some that this is a deficiency in the language, and the control structure should be added. This paper demonstrates that not only is...
Python's match-case differs significantly from traditional switch-case statements found in languages like Java or C++. In Java, for example, the switch statement is limited to matching only scalar values (like integers and enum types), whereas Python's match-case offers a much more flexible pat...
switch()方法采用参数'month'并将其转换为字符串,然后将其附加到大小写文字中,然后将其传递给getattr()方法,然后返回该类中可用的匹配函数。 如果找不到匹配项,则getattr()方法将返回lambda函数作为默认值。 字典映射替换 #Functiontoconvertnumberintostring #Switcherisdictionarydatatypehere defnumbers_to_strings(arg...
forin<sequence>:<statement><statement> 流程图如下: 自定义循环变量var遍历sequence序列中的每一个值,每个值执行一次循环的语句块。sequences表示序列,常见类型有list(列表)、tuple(元组)、strings(字符串)和files(文件)。下面的代码是计算1到100的求和,输出三角形星号的示例。 代码语言:javascript 代码运行次数:0 ...
说明:首先,创建一个名为PythonSwitchStatement定义一个switch()方法。它还针对特定的不同情况定义了其他功能。 的switch()方法采用参数'month'并将其转换为字符串,然后将其附加到大小写文字中,然后将其传递给getattr()方法,然后返回该类中可用的匹配函数。

statement_block_1 elif condition_2: statement_block_2 else: statement_block_3 Python 中用 elif 代替了 else if,所以if语句的关键字为:if – elif – else。 注意: 1、每个条件后面要使用冒号 :,表示接下来是满足条件后要执行的语句块。 2、使用缩进来划分语句块,相同缩进数的语句在一起组成一个语句块...
