在一行中打印每个单词而不是 Python 中的字符？

Question

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:    print(each_item) 输出 1：代码2：ls = ["one is one","two is two","three is three"]for each_item in ls:    for each_word in each_item:        print(each_word)输出 2：我的意图是打印如下一是一二是二三是三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)

one

is 

one

two

is

two

three

is

three
