[已解决]求助：python逐行读取，删除以某个字符开头的字符串

poppy章鱼

求助，怎么实现这个功能？感激不尽~

输入文件示例：

1. OG0000000: aa|TbCa001702 aa|TbCa001961 aa|TbCa002485 bb|TbCa002794 bb|TbCa003025 cc|TbCa003100 dd|TbCa003129 ee|TbCa003206 bb|TbCa003139
   
2. OG0000001: aa|AT1G08070 aa|AT1G20230 bb|AT1G31920 bb|AT1G59720 bb|AT1G68930 cc|AT1G74630 cc|AT2G01510 dd|AT2G03880 dd|AT2G29760
   
3. OG0000002: aa|R002G044500 aa|R002G044700 bb|R002G044900 bb|R002G045000 bb|R002G079000 cc|R003G073100 dd|R004G270600 ee|R007G319800

复制代码

输出结果：

1. OG0000000: aa|TbCa001702 aa|TbCa001961 aa|TbCa002485 bb|TbCa002794 bb|TbCa003025 bb|TbCa003139
   
2. OG0000001: aa|AT1G08070 aa|AT1G20230 bb|AT1G31920 bb|AT1G59720 bb|AT1G68930
   
3. OG0000002: aa|R002G044500 aa|R002G044700 bb|R002G044900 bb|R002G045000 bb|R002G079000

复制代码

假如每行中冒号之后，以空格分割的字符串'|'管道符前面为cc, dd, ee，则删除这个字符串，其他的正常输出。
比如第一行中cc|TbCa003100 dd|TbCa003129 ee|TbCa003206 以cc, dd，ee开头，则删除，只输出其他的aa|TbCa001702 aa|TbCa001961 aa|TbCa002485 bb|TbCa002794 bb|TbCa003025 bb|TbCa003139
