When we have a for loop inside another for loop, it’s called a nested for loop. There are multiple applications of a nested for loop. Consider the list example above. The for loop prints out individual words from the list. But what if we want to print out the individual characters of...
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. (...
我们可以根据顺序来for循环遍历整个list。使用string和tuple的时候也可以这样子for loop 遍历。这是非常符合代码直觉的,因为遍历的都是有序的对象。然而我们使用字典的时候,无序的对象我们依然能够进行for loop遍历。 因为for loop要求对象是一个可迭代的对象(iterable)。 it=iter(fruits)print(next(it))#打印fruits[...

假设我们有一个数字 list(列表)以及一个生成这些数字的平方的 generator(生成器): 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>numbers=[1,2,3,5,7]>>>squares=(n**2forninnumbers) 我们可以将我们的 generator 对象传给tuple构造函数来变成一个 tuple(元组): ...
对于list和tuple,编号顺序即为元素原先的排列顺序。enumerate()也是可迭代对象,其每个元素的类型为tuple,每个tuple均含有2个元素,具体即为 (序号, 原先的元素)。在for关键字后面,按顺序使用两个循环变量,即可分别接住每个元素的序号和其自身: >>> L = ['a','b','c','d','e','f','g','h','i','...
In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e

滿多東西都可以作為「可迭代物」(iterable),以函式(Function)來說的話,常見的包括range()、enumerate()、zip()、reversed()、sorted();以資料型態來說的話,包括字串(string)、串列(list)、元組(tuple)、字典(dictionary)。 這個段落,將為你說明for陳述句如何與這些「可迭代物」(iterable)一同運作。
