Regex字符串模式插入操作

Question

输入字符串：

蛋白酶激活受体-2(IS)-1α、-8、-97、-2α和-3是特异性拮抗剂。角质形成细胞的LL-37、-15、SAC-1、-7和-21较好。

输出字符串：

蛋白酶激活受体-2(IS)-1α，皮肤间(IS)-8，皮肤间(IS)-97，皮肤间(IS)-2α，-3为特异性拮抗剂。角质形成细胞的LL-37、LL-15、SAC-1、SAC-7和SAC-21较好。

预期输出为：

蛋白酶激活受体-2皮肤间(IS)-1α，皮肤间(IS)-8，皮肤间(IS)-97，皮肤间(IS)-2α和皮肤间(IS)-3为特异性拮抗剂.角质形成细胞的LL-37、LL-15、SAC-1、SAC-7和SAC-21较好。

我不会在输出字符串中获得interskin (IS)-3部件。请查看我的代码并提出解决方案。

import re
string_a = "The Proteinase-Activated Receptor-2 interskin (IS)-1ALPHA, -8, -97, -2ALPHA, and -3 was specific antagonist. The LL-37, -15, SAC-1, -7, and -21 in keratinocytes was good."
print(string_a)
pattern = re.compile(r"\b([A-Za-z]+\s*\([A-Z]+\)|[A-Z]+)(\s*-\d+[A-Z]+(?:,*\s*-\d+)*|\s*-\d+(?:,*\s*-\d+)*)(?:,*\s*and\s+(-\d+))?")
print('\n')
print(pattern.sub(lambda x: x.group(1) + f', {x.group(1)}'.join(map(str.strip, x.group(2).strip().split(','))) + (f' and {x.group(1)}{x.group(3)}' if x.group(3) else ''), string_a))

Answer 1

使用您的模式和代码，您可以在第二个替换的组末尾添加匹配的可选大写字符[A-Z]*。

\b([A-Za-z]+\s*\([A-Z]+\)|[A-Z]+)(\s*-\d+[A-Z]+(?:,*\s*-\d+[A-Z]*)*|\s*-\d+(?:,*\s*-\d+)*)(?:,*\s*and\s+(-\d+))?
                                                           ^^^^^^

输出

蛋白酶激活受体-2皮肤间(IS)-1α，皮肤间(IS)-8，皮肤间(IS)-97，皮肤间(IS)-2α和皮肤间(IS)-3为特异性拮抗剂.角质形成细胞的LL-37、LL-15、SAC-1、SAC-7和SAC-21较好。
