這篇文章主要介紹了Python去除字符串兩端空格的方法,本文主要講解了string.lstrip、string.rstrip、string.strip等函數的運用,需要的朋友可以參考下
目的
獲得一個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處理：
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.
具體的效果如下：
代碼如下:
In [10]: x=' Hi,Jack! '
In [11]: print '|',x.lstrip(),'|',x.rstrip(),'|',x.strip(),'|'
| Hi,Jack! | Hi,Jack! | Hi,Jack! |
其中提供的參數chars用來刪除特定的符號，注意空格並沒有被移除，例如：
代碼如下:
In [12]: x='yxyxyxxxyy Hello xyxyxyy'
In [13]: print x.strip('xy')
Hello
