In this article, will learn how to split a string based on a regular expression pattern in Python. The Pythons re module’sre.split()methodsplit the string by the occurrences of the regex pattern, returning a list containing the resulting substrings. After reading this article you will be ab...

Python正则表达式与split()方法一起使用 import re #split 只能实现单个字符串的分割 string="guoshun is a good boy" print(string.split(' ')) #但是如果中间又好几个空格 那么split耶只能分割一个空格 string2="guoshun is good boy" #regex提供了split方法 print(re.split("\s+",string2)) #也可以同...
The pattern that you pass tore.split()handles a complex string splitting scenario where you’d be hopelessly lost and in the weeds when using the string method.split(). Here’s a list of the regex constructs that you used to make this split happen: ...
下面的String: 由于空格数量不一致,有的多,有的少,这时就需要使用正则表达式了,首先引入re模块: 定义一个正则表达式并编译成Pattern对象: 然后用Pattern对象Split:

`RegexObject` 的 split() 方法在 RE 匹配的地方将字符串分片,将返回列表。它同字符串的 split() 方法相似但提供更多的定界符;split()只支持空白符和固定字符串。就象你预料的那样,也有一个模块级的 re.split() 函数。 split(string [, maxsplit = 0]) ...
