thistuple = ("apple", "banana", "cherry") for i in range(len(thistuple)): print(thistuple[i]) Try it Yourself » Using a While LoopYou can loop through the tuple items by using a while loop.Use the len() function to determine the length of the tuple, then start at 0 and ...
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. (...
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[0]print(next(it))#打印fruits[1]pri...
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...

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。
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 specifyingiteration, which allows code to ...
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

Aforloop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like theforkeyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. ...
