python - 提取最后一次出现的大括号之间的文本

Question

我有这样的字符串，

Protein XVZ [Human]
Protein ABC [Mouse]
Protein CDY [Chicken [type1]]
Protein BBC [type 2] [Bacteria]

输出应该是，

Human
Mouse
Chicken [type1]
Bacteria

因此，我想要最后一对大括号内的所有内容。必须像上一个示例一样忽略该对之前的大括号。有没有一种有效的方法可以在 Python 中执行此操作？预先感谢您的帮助。

Answer 1

这个怎么样:

import re
list = ["Protein XVZ [Human]","Protein ABC [Mouse]","go UDP[3] glucosamine N-acyltransferase [virus1]","Protein CDY [Chicken [type1]]","Protein BBC [type 2] [Bacteria] [cat] [mat]","gi p19-gag protein [2] [Human T-lymphotropic virus 2]"]
pattern = re.compile("\[(.*?)\]$")
for string in list:
    match = re.search(pattern,string)
    lastBracket = re.split("\].*\[",match.group(1))[-1]
    print lastBracket
