Hello. I've had this problem in PHP also. I want to create a for loop that will iterate over so many split words in a list and for each of the items the loop will add an item to another list based on the original item being iterated over. I don't know why I suffer with this...
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_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,我们学习了如何使用Python的循环将数据添加到新列表中。我们...

Python for loop Pankaj Kumar 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 ...
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...
