使用 Python 正则表达式按换行符或句点划分字符串 [英] Divide string by line break or period with Python regular expressions

问题描述

我有一个字符串:

"""你好，很高兴认识你.我的名字是鲍勃."""

我正在尝试找到将其拆分为按句点和换行符划分的列表的最佳方法:

["你好", "很高兴认识你", "我叫鲍勃"]

我很确定我应该使用正则表达式，但是，由于没有使用它们的经验，我正在努力弄清楚如何做到这一点.

解决方案

你不需要正则表达式.

<预><代码>>>>txt = """你好，很高兴认识你.... 我的名字是鲍勃.""">>>txt.split('.')['你好', "很高兴认识你", '\n我叫鲍勃', '']>>>[x for x in map(str.strip, txt.split('.')) if x]['你好', "很高兴认识你", '我叫鲍勃']

I have a string:

"""Hello. It's good to meet you.
My name is Bob."""

I'm trying to find the best way to split this into a list divided by periods and linebreaks:

["Hello", "It's good to meet you", "My name is Bob"]

I'm pretty sure I should use regular expressions, but, having no experience with them, I'm struggling to figure out how to do this.

解决方案

You don't need regex.

>>> txt = """Hello. It's good to meet you.
... My name is Bob."""
>>> txt.split('.')
['Hello', " It's good to meet you", '\nMy name is Bob', '']
>>> [x for x in map(str.strip, txt.split('.')) if x]
['Hello', "It's good to meet you", 'My name is Bob']
