In the programs we have seen till now, there has always been a series of statements faithfully executed by Python in exact top-down order. What if you wanted to change the flow of how it works? For example, you want the program to take some decisions and do different things depending ...
The if statement in Python is similar to that found in other programming languages (such as Java). It's the backbone of the logical flow of most programs. Here's an example:Python Copy y = 6 if y % 2 == 0: print('Even') The output is:...
Python Control Flow - Explore Python control flow statements including if, else, and loops to manage the execution of code efficiently.
match/case 模式匹配, 和 C 里面的多分支字面量匹配 switch 不太一样的是,python 中的 match 可以做到结构解析和匹配(例如解包序列和变量的绑定匹配等等)。 注意: 该基础语法需要 python 3.10 ++ '_' 也称为 don't care pattern,通常用于最后一个 case。也可以使用变量,比如 others 代替。 使用or pattern ...
In this chapter, we will learn about various flow control statements. What are the Flow Control Statements? A Flow Control Statement defines the flow of the execution of the Program. There are 7 different types of flow control statements available in Python: if-else Nested if-else for while ...
Python Tutorial 学习(四)--More Control Flow Tools 4.1 if 表达式 作为最为人熟知的if.你肯定对这样的一些表达式不感到陌生: >>>x=int(raw_input("Please enter an integer: "))Please enter an integer: 42>>>ifx<0:...x=0...print'Negative changed to zero'...elifx==0:...print'Zero'......

6.8 控制流语句(Control Flow Statement) 程序最小的独立单元是语句(statement),语句一般由分号结尾,缺省情况下,语句是顺序执行的,但是当涉及逻辑判断控制时,就要求有控制流程序语句。控制流程序语句分为条件语句和循环语句,在C语言中,条件语句有if、if-else、switch等,而循环过程则由while、do-while和for语句支持。
[译]The Python Tutorial#More Control Flow Tools 除了刚才介绍的while语句之外,Python也从其他语言借鉴了其他流程控制语句,并做了相应改变。 4.1ifStatements 或许最广为人知的语句就是if语句了。例如: x =int(input("Please enter an integer: "))ifx <0: ...
The programs we’ve written so far are straight-line programs that consist of a sequence of Python statements executed one after the other. The flow of execution is simply a straight sequence of statements, with no branching or looping back to previous statements. In this chapter, we look at...
