正则表达式python查找金额和单词，以防该金额位于段落末尾
我需要罚款美元金额和文字后，在每一个案件的金额和文字是不可用的，那么我应该只有美元金额。在这种情况下，美元金额放在段落末尾。 这是一个示例段落正则表达式python查找金额和单词，以防该金额位于段落末尾,python,regex,split,words,Python,Regex,Split,Words,我需要罚款美元金额和文字后，在每一个案件的金额和文字是不可用的，那么我应该只有美元金额。在这种情况下，美元金额放在段落末尾。 这是一个示例段落 The cumulative effect resulted in a charge to incomeof $1,001.9 million (after reduction for income taxes of $6.4 million) in fiscal2001.

没有正则表达式，您可以轻松完成这项任务
['$' + ' '.join(line.split(" ")[:2]) for line in text.split("$")[1:]]
到目前为止，你尝试了什么？你在这里做了很多事情，千位和标点符号让事情变得复杂。我认为正则表达式是不可靠的，因为你把它从语言中挑选出来。@Nutmag64我试图用[\$]{1}[\d，]+\.？\d{0,2}（\w+）@sln来查找金额。我尝试了类似[\$]{1}[\d，]+\.\d{0,2}（\w+）的方法，但在该段中遗漏了一些金额，所以我想尝试找到解决方案。事实上，我试图先找到美元金额，然后用空格分割所有段落，然后使用索引，但最后一段（0.02美元）不起作用。所以我想解决它。。。
