考虑以下代码和输出

代码1：

ls = ["one is one","two is two","three is three"]

我需要在哪里修改以按所需顺序打印？

Answer 1

试试这个：ls = ["one is one","two is two","three is three"]words = []for each_item in ls:    words = each_item.split()    for word in words:        print(word)

Answer 2

您希望在迭代之前拆分每个句子。这是因为，默认情况下，当您在 Python 中遍历字符串时，它将逐个字符地进行。通过调用split，您可以将字符串（按空格）拆分为单词列表。见下文。ls = ["one is one","two is two","three is three"]for sentence in ls:    for word in sentence.split():        print(word)oneis onetwoistwothreeisthree
