如何找到“导入名称" Python中的任何软件包? [英] How to find "import name" of any package in Python?

问题描述

我想知道是否有任何可靠且一致的方法来获取Python包的导入名称"/名称空间.例如；

I wonder if is there any reliable and consistant way to get a Python package's "import name" / namespace. For example;

包装； django-haystack
导入名称；干草堆

Package; django-haystack
Import name; haystack

或

包装； ipython
导入名称； IPython

Package; ipython
Import name; IPython

到目前为止，我知道，PyPi不会存储我使用PyPiXmlRpc检查过的信息.

So far I know, PyPi doesn't store that information that I've checked with PyPiXmlRpc.

我还尝试自动下载软件包，解压缩并挖掘.egg-info，但有些软件包根本没有该文件夹.

I also tried to automate to download the package, extract it and dig the .egg-info but some packages doesn't have that folder at all.

任何帮助将不胜感激，并将用于制作精美的小工具:)

Any help will be appreciated and will be used for a good-manner gadget :)

推荐答案

请注意，您在此处所说的包不是包，而是发行版.分布可以包含零个或模块，模块或程序包.这意味着不存在分发到软件包的一对一映射.

Note that what you call a package here is not a package but a distribution. A distribution can contain zero or modules modules or packages. That means there is no one-to-one mapping of distributions to packages.

除了实际安装并检查新添加的软件包，模块和pth文件的文件系统更改外，我不确定是否有办法检测发行版将安装哪些模块和软件包.

I'm not sure there is a way to detect what modules and packages will be installed by a distribution, other than actually installing it and introspect filesystem changes for newly added packages, modules and pth files.
