Simonepython replace函数 如何做到仅第一处不被替换？
的有关信息介绍如下：
# coding: utf-8 s = "python title \n a new line \n second line" # 字符串 sep = " \n " # 分隔符 new_sep = "" # 换行替换成空字符串 newline_count = s . count ( sep ) # 分隔符出现次数 token_list = s . rsplit ( sep , newline_count - 1 ) # rsplit函数保留第一个sep print ( new_sep . join ( token_list )) # 使用new_sep拼接字符串
