这篇文章主要介绍了Python去除字符串两端空格的方法,本文主要讲解了string.lstrip、string.rstrip、string.strip等函数的运用,需要的朋友可以参考下

　　目的

　　获得一个首尾不含多余空格的字符串

　　方法

　　可以使用字符串的以下方法处理：

　　string.lstrip(s[, chars])

　　Return a copy of the string with leading characters removed. If chars is omitted or None, whitespace characters are removed. If given and not None, chars must be a string; the characters in the string will be stripped from the beginning of the string this method is called on.

　　string.rstrip(s[, chars])

　　Return a copy of the string with trailing characters removed. If chars is omitted or None, whitespace characters are removed. If given and not None, chars must be a string; the characters in the string will be stripped from the end of the string this method is called on.

　　string.strip(s[, chars])

　　Return a copy of the string with leading and trailing characters removed. If chars is omitted or None, whitespace characters are removed. If given and not None, chars must be a string; the characters in the string will be stripped from the both ends of the string this method is called on.

　　具体的效果如下：

　　 代码如下:

　　In [10]: x=' Hi,Jack! '

　　In [11]: print '|',x.lstrip(),'|',x.rstrip(),'|',x.strip(),'|'

　　| Hi,Jack! | Hi,Jack! | Hi,Jack! |

　　其中提供的参数chars用来删除特定的符号，注意空格并没有被移除，例如：

　　 代码如下:

　　In [12]: x='yxyxyxxxyy Hello xyxyxyy'

　　In [13]: print x.strip('xy')

　　Hello
