第一版本：修改名字文件，不对序列处理
比如序列名字如下，仅仅需要物种名字

利用python脚本加正则表达处理；
思路：正则匹配 “[” “]”这俩符号，然后为列表，读取列表的-1索引
import re import sys for line in open(sys.argv[1], 'r'): my = re.findall(r'[([sS]+?)]',line) print (my[-1])
使用：python 脚本.py 名字文件.txt > new_name.txt
结果
Clostridioides difficile Providencia rettgeri Clostridioides difficile Pseudomonas sp. D1HM Clostridioides difficile P59 Xenorhabdus nematophila AN6/1 Clostridioides difficile Clostridioides difficile Lentinula edodes Xenorhabdus nematophila Providencia alcalifaciens Clostridioides difficile Clostridioides difficile Pseudomonas sp. NFPP19
第二版本 待更新（更新实用的正则表达用法，外加序列，彻底解决序列名字问题）
