Python去除字符串两端空格的方法
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：
复制代码 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：
复制代码 代码如下:
In [12]: x=\’yxyxyxxxyy Hello xyxyxyy\’
In [13]: print x.strip(\’xy\’)
Hello
