什么是多文本的最佳正则表达式？

Question

文件内容如下：

#encoding=utf8
__author__ = "naci"
__title__ = "test script"
__desc__ = "test description" 
or __desc__ = """
    test description.
"""
# start your script here

问题：      什么是获得作者，头衔和desc的最佳正则表达式？ ＆＃34;＆＃34;也许＆＃39;＆＃39;或＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;也许＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;

Answer 1

考虑使用re.findall()函数：

import re

s = '''
#encoding=utf8
__author__ = "naci"
__title__ = "test script"
__desc__ = "test description"
or __desc__ = """
    test description.
"""
'''

data = re.findall(r'__(?P<attr>\w+)_ = (?P<val>"[^"]+"|"""[^"]+""")', s)
print(data)

输出（对：键/值）：

[('author_', '"naci"'), ('title_', '"test script"'), ('desc_', '"test description"'), ('desc_', '"""\n    test description.\n"""')]
