在python句子结尾处删除句点 [英] Remove periods at the end of sentences in python

问题描述

我有这样的句子-这是一个测试.4.55和5,000." 我想删除句子结尾处的句点，但不要删除数字之间的句点.我的输出必须是-这是测试4.55和5,000" 我尝试了以下选项，但未获得所需的输出:

I have sentences like this - "this is a test. 4.55 and 5,000." I want to remove the period at the end of the sentences, but not between numbers. My output has to be - "this is a test 4.55 and 5,000" I tried the below options, but not getting the required output:

wordList = "this is a test. 4.55 and 5,000."
pattern3 = re.compile("[^\w\d]+")
wordList = pattern3.sub(' ',wordList)

还尝试了以下2种方法:

Also tried the below 2:

pattern3 = re.compile("[^\w]|^[0-9]\.[0-9]")
pattern3 = re.compile("[^\w]|^([0-9]/.[0-9]+)")

我不知道我要去哪里.有人可以给我一些指示吗?我搜索了较早的帖子并进行了尝试，但它们不适用于我的情况.

I don't know where I am going wrong. Can someone give me some pointers? I searched the earlier posts and tried them, but they are not working for my situation.

推荐答案

尝试否定前瞻:

\.(?!\d)

此匹配项是任何不带数字的句点.

What this matches is any period that's not followed by a digit.
