声明:s为字符串,rm为要删除的字符序列
s.strip(rm) 删除s字符串中开头、结尾处,位于 rm删除序列的字符
s.lstrip(rm) 删除s字符串中开头处,位于 rm删除序列的字符
s.rstrip(rm) 删除s字符串中结尾处,位于 rm删除序列的字符
注意:
1. 当rm为空时,默认删除空白符(包括'\n', '\r', '\t', ' ')
例如:
>>> a=' Hello World '
>>> a
' Hello World '
>>> a.strip()
'Hello World' >>> x='\t\r\npython'
>>> x
'\t\r\npython'
>>> x.strip()
'python'
2.rm删除序列是只要边(开头或结尾)上的字符在删除序列内,就删除掉。
例如:
>>> aString='123love'
>>> aString
'123love'
>>> aString.strip('')
'3love'
