语法:str.rsplit(sep=None, maxsplit=-1) -> list of strings 返回 字符串列表 或str.rsplit(sep=None, maxsplit=-1)[n] 参数: sep —— 分隔符,默认为空格,但不能为空即(")。 maxsplit —— 最大分割参数,默认参数为-1。 [n] —— 返回列表中下标为n的元素。列表索引的用法。
S.rsplit(sep=None, maxsplit=-1) -> list of strings Return a list of the words in S, using sep as the delimiter string, starting at the end of the string and working to the front. If maxsplit is given, at most maxsplit
