Python 从纯文本输入文件下的2个不同函数中提取从$开始的所有字符串

我有一个ascii纯输入文本文件，如下所示，有很多大小写，我在这里给出了两个开关大小写。我需要的是，我需要在下面的文本文件中提取所有以“$”开头的字符串，并将其放入新的文件1中。然后我需要在下面的textfile中提取以“$”开头的所有字符串（粗体），并放入新文件2中。 我期待这样的输出：

预期输出位于文件1中：

---

$severity、$description、$eventID、$eventURL、$alertLevel、$eventStart、$eventSourceCount

    case "15": ### eventWormLow

    case "15": ### eventWormLow

$severity、$description、$eventID、$eventURL、$alertLevel、$eventStart、$eventSourceCount、$eventSourceTable、$eventDestCount、$eventDestTable、$eventProtocolCount、$eventProtocolTable、$eventServiceCount、$eventServiceTable、$mazuSourceName

预期输出位于文件2中：

---

$severity、$description、$eventID、$eventURL、$alertLevel、$eventStart、$eventSourceCount

    case "15": ### eventWormLow

    case "15": ### eventWormLow

$severity、$description、$eventID、$eventURL、$alertLevel、$eventStart、$eventSourceCount、$eventSourceTable、$eventDestCount、$eventDestTable、$eventProtocolCount、$eventProtocolTable、$eventServiceCount、$eventServiceTable、$mazuSourceName

输入文件（普通ascii）：

我试过了，效果很好。

你两小时前问过同样的问题：不，这是不同的。有人知道怎么做吗？
