我正在尝试使用 Python 从 Packages.gz 文件中提取 debian 包的描述。有没有办法只获取包的描述，即Description: 字段后的内容。

源文件是：

Package: 2vcard

Description: perl script to convert an addressbook to VCARD file format
 2vcard is a little perl script that you can use to convert the
 popular vcard file format. Currently 2vcard can only convert addressbooks
 and alias files from the following formats: abook,eudora,juno,ldif,mutt,
 mh and pine.
 .
 The VCARD format is used by gnomecard, for example, which is used by the
 balsa email client.

也许http://pypi.python.org/pypi/python-debian会有所帮助？

详细地说，假设data是一个包含源文件内容的字符串，那么：

from debian import deb822
print deb822.Deb822(data.split("\n"))['Description']

将输出描述
