while-loop 将运行直到表达式测试为真。will run while the expression that we test for is true. 关键字"break" 用来跳出循环。而关键字”continue”用来不执行余下的部分而直接跳到下一个循环。 for-loop表达式查看一个字符串列表 (字符串用空格分隔) 然后将其赋给一个变量: ...
making them a good choice for basic array looping. ‘While’ and ‘until’ loops offer more control over the loop condition, which can be useful in more complex scenarios. However, they require you to manually manage a counter variable, which can lead to off-by-one errors if you’re not...
whileloops are useful in scripts that depend on a certain condition to be true or false, but you can also use them interactively to monitor some condition. The important things to remember are: Always be clear about what is the condition toendthe loop. If that is something that you expect...
