Question

我的代码有问题。我有一个文本文件，并且在此文本文件中是一千个来自句子的带标签的/下一行的单词。我的问题是我想还原此文本文件中的单词，然后再次使其成为句子。

我想过一种制作for循环语句的方法，如果它到达点with('test','r') as f: text = f.open() sentence = [] sentences = [] for words in text: if words != "." sentence.append(words) elif words == "." sentence.append(words) sentences.append(sentence) sentence = [] #Sample output #[['This', 'is', 'a', 'sentence', '.'], ['This', 'is', 'the', 'second', 'sentence', '.'], #['This', 'is', 'the', 'third', 'sentence', '.']],，那么它将把句子存储在列表中。

#This is the text file
This
is
a
sentence
.
This
is
the
second
sentence
.
This
is
thr
third
sentence
.

代码有点奏效，但是有点复杂。我发现了一个简短而又不太复杂的主意。预先谢谢你。

Answer 1

您可以使用str.split()。

例如：

text = 'First sentence. Second sentence. This is the third sentence. '
text.split('. ')[:-1]
>>> ['First sentence', 'Second sentence', 'This is the third sentence']

如果要包含。必须这样做：

text = 'First sentence. Second sentence. This is the third sentence. '
split_text =  [e+'.' for e in text.split('. ')][:-1]
split_text
>>> ['First sentence.', 'Second sentence.', 'This is the third sentence.']

Answer 2

以下是同一个衬里，如果需要更多帮助，请告诉我：

sentences = open('test','r').read().split('\.')

Answer 3

这非常简单。从文件中读取，按句点分成几行，按任何空格分隔每一行，用单空格重新加入行，将句点退回到句子末尾。

sentences = [' '.join(x.split()) + '.' for x in open('test','r').read().split('.')]
