FOR_LOOP --> NUMBER_LIST : iterates over FOR_LOOP --> NEW_NUMBER_LIST : appends to 这个关系图显示了FOR_LOOP循环与NUMBER_LIST和NEW_NUMBER_LIST之间的关系。循环通过迭代NUMBER_LIST中的元素,并将结果添加到NEW_NUMBER_LIST中。 总结 通过本文,我们学习
StartCreateListForLoopAddToNewListEnd 以上流程图展示了整个操作的过程:从创建包含数字的列表开始,然后通过for循环遍历每个数字,最后将每个数字的平方添加到新列表中。 状态图 为了更好地理解操作过程中的状态变化,我们可以使用状态图来表示: Create a new listBegin for loopAdd item to listContinue for loopEnd ...
for i in range(len(thislist)): print(thislist[i]) Try it Yourself » The iterable created in the example above is [0, 1, 2].Using a While LoopYou can loop through the list items by using a while loop.Use the len() function to determine the length of the list, then start ...

The for loop in Python is an iterating function. If you have a sequence object like alist, you can use the for loop to iterate over the items contained within the list. The functionality of the for loop isn’t very different from what you see in multiple other programming languages. ...

In Python, we use a for loop to iterate over sequences such as lists, strings, dictionaries, etc. For example, languages = ['Swift', 'Python', 'Go'] # access elements of the list one by one for lang in languages: print(lang) Run Code Output Swift Python Go In the above example...
Review: Python’s for loop Python 中的 for 循环不是传统的 for 循环。为了解释我的意思,我们来看一下其他语言的 for 循环是怎么写的。...Python 的 for 循环都把这些工作为我们做了。 所以在 Python 中确实有 for 循环,但不是传统的 C 风格的 for 循环。我们称之为 for 循环的东西的工作方式很...
in is a keyword that connects the loop variable with the iterable. iterable is a data collection that can be iterated over. consists of one or more statements to execute in each iteration.Here’s a quick example of how you can use a for loop to iterate over a list:Python ...
Python中的for循环,没你想的那么简单~ 一年四季,循环往复:说到底就是一个循环的问题 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:...
