考虑以下代码和输出

代码1 ：

ls = ["one is one","two is two","three is three"]
for each_item in ls:

在哪里需要修改以按期望的顺序打印？

Answer 1

根据taoufik的评论，您想在迭代每个句子之前split。这是因为，默认情况下，当您在Python中遍历字符串时，它将逐字符进行。通过调用split，您可以将字符串（按空格）分成单词列表。见下文。

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

for sentence in ls:
    for word in sentence.split():
        print(word)

one
is 
one
two
is
two
three
is
three

Answer 2

尝试一下：

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)
