If you knewpythonthenbreakandcontinuebehavior is the same in python too. But python provides one more loop control statement called apass. Passis like anullstatement and the interpreter will read it but will not perform any operation. It simply results in no operation. Bash doesn’t provide a...
Line 7performs a check using anifstatement. When the variable equals two ("$i" == 2), the program exits thewhileloop using the Bashbreakstatement online 10. In that case, the code jumps toline 16. If the variable is a different number, the script continues as expected online 12. Exec...

Loops allow you to run one or more commands multiple times until a certain condition is met. In Bash, break and continue statements allows you to control the loop execution.
Bash Copy在这个例子中,我们使用了while循环,当i小于或等于5时,执行循环体内的代码。我们使用if语句来检查是否达到3,如果达到3,我们使用break语句停止循环。在循环结束后,我们输出一条消息。break语句的应用场景break能够应用到很多的场景,比如说:在循环中查找元素:如果找到了要查找的元素,则可以立即停止循环。 在循环...
How does let in for loop work? I understand how "var" works and I'm quite used to it - the scope is functional. However the let statement is far from clear. I understand is has block scope, but why does THAT matter in the......
