Consider using re.findall() function:

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)

The output(pairs: key/value):

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