我们都知道，在 Java 的时候如果需要使用 for loop 循环，首先需要定义一个 i，然后进行循环。比如说，我们要循环 1 到 501，Java 的代码为：for(int i=1; i<501; i++)Python 把这个循环进行简化了。我们可以使用下面的代码来在 Python 中执行循环：for i in range(1, 501):直接使用一个 range 函数。...
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. (...
在python中,要实现“重复、自动地执行代码”,有两种循环语句可供我们选择使用: 一种是for...in...循环语句,另一种是while循环语句。 一、for循环: for循环格式: 代码示例 代码语言:javascript 代码运行次数:0 运行 AI代码解释 foriin[1,2,3,4,5]:print(i) 运行效果图: 当然这里循环的不仅仅可以是列表,...
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...

In this article, you’ll learn what is for loop in Python and how to write it. We use a for loop when we want to repeat a code block a fixed number of times. A for loop is a part of a control flow statement which helps you to understand the basics of Python. Also, Solve:...

The simplified “for loop” in Python is one line for loop, which iterates every value of an array or list. The one line for the loop is iterated over the “range()” function or other objects like an array, set, tuple, or dictionary. ...
The loop ends after the body of the loop is executed for the last item. Indentation in Loop In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, ...
for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。 for语句其实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: In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows...
