python的partition() 方法

本文介绍了Python中字符串的partition方法,该方法用于根据指定的分隔符将字符串分割为三部分,并返回一个包含这三个部分的元组。通过示例演示了如何使用此方法。

描述

partition() 方法用来根据指定的分隔符将字符串进行分割。

如果字符串包含指定的分隔符,则返回一个3元的元组,第一个为分隔符左边的子串,第二个为分隔符本身,第三个为分隔符右边的子串。

partition() 方法是在2.5版中新增的。

语法

partition()方法语法:

str.partition(str)

参数

str : 指定的分隔符。

 

返回值

返回一个3元的元组,第一个为分隔符左边的子串,第二个为分隔符本身,第三个为分隔符右边的子串。

 

实例

 

以下实例展示了使用 partition() 方法的使用:

#!/usr/bin/python

str = "http://www.w3cschool.cc/"

print str.partition("://")

输出结果为:

('http', '://', 'www.w3cschool.cc/')
