Python comes with two inbuilt keywords to interrupt loop iteration,breakandcontinue. Break Keyword In While loop The break keyword immediately terminates the while loop. Let's add a break statement to our existing code, x =1while(x<=3):print(x) x = x +1ifx ==3:breakelse:print("x is...
Computer programs are great to use for automating and repeating tasks so that we don’t have to. One way to repeat similar tasks is through usingloops. We’ll be covering Python’swhile loopin this tutorial. Awhileloop implements the repeated execution of code based on a givenBooleancondition...
ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself » Note:remember to increment i, or else the loop will continue forever. Thewhileloop requires relevant variables to be ready, in this example we need to def...
Loops are used to repeatedly execute a block of program statements. The basic loop structure in Python is while loop. Here is the syntax. Syntax: while (expression) : statement_1 statement_2 ... The while loop runs as long as the expression (condition) evaluates to True and execute the ...
如果你對for迴圈或if陳述句不熟悉,可以閱讀〈Python for 迴圈(loop)的基本認識與7種操作〉、〈Python if 陳述句的基礎與3種操作〉。 Python while 迴圈句基本認識 先來看一個簡單的while迴圈。 例子是這樣的,你要用Python印出1到100。你可以設定一個變數i,並在while後頭陳述符合需求的條件,條件是只要i小於...
>>>whilen>0:n-=1;ifTrue:print('foo')SyntaxError: invalid syntax Remember thatPEP 8discourages multiple statements on one line. So you probably shouldn’t be doing any of this very often anyhow. Conclusion In this tutorial, you learned aboutindefinite iterationusing the Pythonwhileloop. You’...
Break theloopat counter =128. loop表达式主体执行以下连续操作: 声明stop_loop变量。 指示程序将变量值绑定到loop表达式的结果。 启动循环。 执行loop表达式主体中的操作: 循环主体 将counter值递增为当前值的两倍。 检查counter值。 如果counter值大于 100: ...
解决While loop问题 - Python 当我们在使用while循环时,需要确保循环的终止条件最终会被满足,否则循环将会无限执行下去。通常情况下,我们可以在循环内部修改循环控制变量,使得终止条件得以满足。 1、问题背景 一位开发者在使用 Python 开发一个基于文本的游戏时,遇到了 while 循环的问题。他将游戏代码和音频处理代码...
