Python：从文件中分割句子

Question

我有一个这样的文件 data.txt：

<<a
<<t This is a title 01
/t>>
<<c
This is a sentence. This is a sentence. This is a sentence. This is a sentence.
This is a sentence. This is a sentence. This is a sentence. This is a sentence.
/c>>
/a>>
<<a
<<t This is a title 02
/t>>
<<c
This is a sentence. This is a sentence. This is a sentence. This is a sentence.
This is a sentence. This is a sentence. This is a sentence. This is a sentence.
/c>>
/a>>

我想读取文件并将每个句子拆分为如下列表：

[[This is a title 01],[This is a sentence.],[This is a sentence.]...[This is a title 02],[This is a sentence.]...]

提前感谢您的帮助。

Answer 1

您可以尝试以下方法-

result = []
with open('data.txt', 'r') as f:
  for line in f:
    if "This is a title" in line:
      cleaned_line = line.lstrip('<<t').strip()
      result.append(cleaned_line)
    elif line.startswith("This is a sentence"):
      sentence_list = line.split('.')
      for _ in sentence_list:
        result.append(_)

这是如何工作的？
打开文件，逐行迭代。 提取标题。去掉 <<t 和空格。
要提取句子，只需在句点 (.) 处拆分行字符串。然后将所有内容附加到 result 列表中。
编辑：
注意：您最终将获得一个字符串列表。由于您是 Python 新手，我将把它作为练习留给您，让您将字符串列表转换为列表列表。它应该非常简单。
