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.
theString = 'saaaay yes no yaaaass' print theString.strip('say') theString依次被去除首尾在['s','a','y']数组内的字符,直到字符在不数组内。所以,输出的结果为: yes no 比较简单吧,lstrip和rstrip原理是一样的。注意:当没有传入参数时,是默认去除首尾空格的。
theString = 'saaaay yes no yaaaass' print theString.strip('say') print theString.strip('say ') #say后面有空格 print theString.lstrip('say') print theString.rstrip('say') 运行结果: yes no es no yes no yaaaass saaaay yes no
