Python 拆分编号字符串

我有以下字符串：

1. the main cause of [explosions].
2. any thing [dreaded] that your "teachers" say is "good" for you. soon after, you explode for no reason.
3. what scientists do to make stuff explode.
4. when a sheet of paper explodes into [flames].
2. Everything that is [put in] [front] of you during any given [day].
3. slang for [testosterone]..[steroid] [hormones].
4. A means of evaluating another person's character through a series of [unannounced], [inconspicuous] examinations. Developed by Eddie, it serves to define which people are desirable company and which should not be associated with. As a general rule, a test-passer is a good person while a test-failer is a bad person.
Passing the test results in the joyous [proclamation] that "You pass the test!"
Failure of a test is announced simply by saying "You failed the test." This phrase is often used to show general disdain for a person's existence.
5. It is terrible.

我希望根据数字\n拆分此字符串，但是，对于数字4之类的情况，仅在最后\n个字符上拆分。我想将第一个数字和下一个数字之间的所有内容捕获为结果列表中的单个字符串

首先，使用

.split（'\n'）

在每一行上循环

第二，检查第一个元素是否为数字

第三，我声明了一个空列表和字符串，用于生成我们的最后一个句子，并将每个最后的句子收集到一个列表中

当

.isdigit（）

为True时，我们需要指定最后一句

当

.isdigit（）

为False时，我们需要将字符串附加到 最后一句

• 现在，我们需要将最后一句添加到新列表中。哪一个是 是在哪里做的？（棘手部分）

• 我们的

  最后一句

  在再次分配新的 字符串，即

  .isdigit（）

  中的字符串为True。我们正在检查，

  最后一句是否有数据。如果是，请附加到
  我们的
  新列表

你已经试过什么了？你能给我们一个你想要达到的输出的例子吗？这个问题没有答案。试试这个正则表达式：

re.findall（'（\d+\..*\n？），s）

@MPJ567看看如何创建一个。看起来是一个很好的解决方案，我希望你能进一步解释它，我不太明白它为什么有效，我很想知道，这样我就能更好地在将来应用它。我得到它在换行符上拆分，然后检查第一个字符是否是数字，然后我就丢失了。特别是，我无法理解“if t:”在做什么。@MPJ567补充了解释。由于您对学习感兴趣，我为

new\u list.append（final\u句）

留下了解释部分，它在

for loop

之外为您使用。我想你已经明白了。愉快的学习。您的答案非常接近，我很喜欢学习re.split和zip，但我已经将Shaik的答案标记为答案，因为它保留了数字后的句点。仅供参考，如果您需要数字后的句点，请使用

（\d+\）

-->例如：

data=re.split（r）（\d+\），data）[1:
