for循环后每行打印一个句子

Question

我有一个文本文件，我想1）在其每个句子上进行迭代，然后2）在其句子的每个单词上进行修改以修改其中的一些内容，然后3）打印生成的文本的新版本，每行一个句子

到目前为止，这是我尝试过的：

import my_text

for sentence in my_text.sents():
    for word in sentence:
        if word == "the":
            print("article", end= " ")
        else:
            print("non-article", end= " ")
     if word == sentence[-1]:
        print("\n")

此代码有效，我的文本被修改并每行打印一个句子。 但是，每个句子之间都有一个空行，我想删除它。 例：

article non-article non-article non-article

non-article non-article non-article non-article non-article non-article

article non-article non-article non-article

这就是我想要的：

article non-article non-article non-article
non-article non-article non-article non-article non-article non-article
article non-article non-article non-article

我该怎么办？

Answer 1

问题出在print("\\n") ，end的默认值是"\\n"所以每次print("\\n")它都会打印"\\n\\n" 。 只需使用print() ：

sentences = ["the cat and dog", "the mouse and cat", "the fox and else"]
sentences = [sentence for sentence in map(str.split, sentences)]

for sentence in sentences:
    for word in sentence:
        if word == "the":
            print("article", end=" ")
        else:
            print("non-article", end=" ")

        if word == sentence[-1]:
            print()

产量

article non-article non-article non-article 
article non-article non-article non-article 
article non-article non-article non-article

您可以这样做：

import my_text

for sentence in my_text.sents():
  end = " "
  for word in sentence:
    if word == sentence[-1]:
        end = "\n"
    if word == "the":
        print("article", end=end)
    else:
        print("non-article", end=end)
