python - Python 中的模式替换

Question

寻找一些替代方法来清理包含括号之间信息的表格文件。这将是包含在管道中的第一步，我需要删除括号内的每个值(包含括号)。

我有什么

> Otu00467  Bacteria(100);Gracilibacteria(99);unclassified(99);unclassified(99);unclassified(99);unclassified(99);
> Otu00469  Bacteria(100);Proteobacteria(96);unclassified(96);unclassified(96);unclassified(96);unclassified(96);
> Otu00470  Bacteria(100);Proteobacteria(100);Alphaproteobacteria(100);Rhodospirillales(100);Rhodospirillaceae(100);Azospirillum(54);

我想要的:

 Otu00467   Bacteria;Gracilibacteria;unclassified;unclassified;unclassified;unclassified;
 Otu00469   Bacteria;Proteobacteria;unclassified;unclassified;unclassified;unclassified;
 Otu00470   Bacteria;Proteobacteria;Alphaproteobacteria;Rhodospirillales;Rhodospirillaceae;Azospirillum;

我的第一种方法是用“;”分隔第二列, "(", ")"并进一步加入一切。不错，但太丑了。

谢谢。
