In this case, you know how many iterations you need. Here you need 10 iterations. In such a case use for loop. for loop in Python Syntax of for loop for i in range/sequencee: statement 1 statement 2 statement n In the syntax, i is the iterating variable, and the range specifies ...
In Python, “for-loop” is widely used to iterate over a sequence, list, or any object. For loop avoids multiple usages of code lines to make the program concise and simple. The “One line for loop” is also the form of “for loop” which means that a complete syntax of “for loop...
for cuisine in menu: print(cuisine) 系统输出: 蒸羊羔 蒸鹿尾 烧花鸭 烧雏鸡 烧子鹅 以上我们利用for循环实现了不同的功能。 下面着重介绍一个在for loop中循环使用else语句的例子。else 中的语句会在循环正常执行完的情况下执行。 三、把else语句放进for loop 例5:我们写一个简单的奇数偶数判别代码: 输入:...
Python in the second iteration. Go in the third iteration. for loop Syntax for val in sequence: # run this code The for loop iterates over the elements of sequence in order, and in each iteration, the body of the loop is executed. The loop ends after the body of the loop is execute...
Python中的for语句,没你想的那么简单~ 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 specify...
Python Syntax for variable in iterable: In this syntax, variable is the loop variable. In each iteration, this variable takes the value of the current item in iterable, which represents the data collection you need to iterate over. The loop body can consist of one or more statements...

本文深入探讨了Python编程中的for循环,这是一种循环语句,使程序员能够重复执行一组代码。与其他循环语句并列的是while循环和嵌套循环。for循环的基本结构和用途将在下面进行详细阐述。for循环的语法如下:简单示例一:初始化一个从0到4的列表,循环遍历并打印列表的每个元素:这展示了一个基础的for循环...
