In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly。(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 iteration. (...
Increment the sequence with 3 (default is 1): forxinrange(2,30,3): print(x) Try it Yourself » Else in For Loop 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...
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...
