　　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,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,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：

复制代码代码如下:

In [10]: x=' 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：

复制代码代码如下:

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

In [13]: print x.strip('xy')
Hello
