Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed once per...

在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了f...
Theelsekeyword in aforloop specifies a block of code to be executed when the loop is finished: Example Print all numbers from 0 to 5, and print a message when the loop has ended: forxinrange(6): print(x) else: print("Finally finished!") ...

熟悉Rust和Golang语法的同学肯定对loop用法不陌生,说白了它是While-True的语法糖,即任何写在loop作用域内的代码都会被无限循环执行,直到遇见break。 比如在Golang中可以通过for和大括号的组合实现loop效果—— import"fmt"funcmain(){sum:=0for{sum+=1ifsum==10{break}}fmt.Println(sum)} ...
