Question

示例程序

import re

demostr = "Department of Microbiology and Immunology. Faculty of Tropical Medicine, Mahidol University, Electronic address: pornsawan.lea@mahidol.ac.th."
org = re.search(r"([A-Z][^\s,.]+[.]?\s[(]?)*(Dept|Association|Office|University|Department)[^,\d]*(?=,|\d)", demostr).group()
print(org)

输出

Department of Microbiology and Immunology. Faculty of Tropical Medicine

程序从给定的字符串中提取Organization，Department。如果,之后有Immunology，则效果很好。但是，如果在组织后出现点.，则会提取错误的输出。所需的输出如下所示-

预期输出

Department of Microbiology and Immunology

Answer 1

您在正则表达式中有两点很好用

([A-Z][^\s,.]+[.]?\s[(]?)*(Dept|Association|Office|University|Department)[^,\d]*?(?=,|\.|\d)

您错过的事情

.*-本质上是贪婪的，由于您的需要，您需要使其变得懒惰。
\.-您没有在交替中包含.。

代码

    import re

    demostr = "Department of Microbiology and Immunology. Faculty of Tropical Medicine, Mahidol University, Electronic address: pornsawan.lea@mahidol.ac.th."
    org = re.search(r"([A-Z][^\s,.]+[.]?\s[(]?)*(Dept|Association|Office|University|Department)[^,\d]*?(?=,|\.|\d)", demostr).group(0)
    print(org)
