How to access files inside a Python egg file?
提问by Ripley
This might be a weird requirement but it's what I've run into. I Googled but yield nothing.
这可能是一个奇怪的要求，但这是我遇到的。我用谷歌搜索但一无所获。
I'm coding an application who's using a lot of constant attributes / values recorded in an XML file (they'll not change so a static file), things work fine until I generated an egg file for it.
我正在编写一个应用程序，该应用程序使用了许多记录在 XML 文件中的常量属性/值（它们不会更改为静态文件），在我为它生成一个egg 文件之前，一切正常。
When the logic reaches the XML accessing part, I got one complaint like this: /home/Workspace/my_proj/dist/mps-1.2.0_M2-py2.6.egg/mps/par/client/syntax/syntax.xml
当逻辑到达 XML 访问部分时，我收到了这样的抱怨：/home/Workspace/my_proj/dist/mps-1.2.0_M2-py2.6.egg/mps/par/client/syntax/syntax.xml
Actually I've bundled the XML file in the path above but seems Python doesn't know how to access it.
实际上我已经在上面的路径中捆绑了 XML 文件，但似乎 Python 不知道如何访问它。
The code to access the XML is as...
访问 XML 的代码是...
file_handler = open(path_to_the_file)
lines = file_handler.read().splitlines()
Any idea?
任何的想法？

If you want to access the contents inside the .egg file you can simply rename it and change extension from .egg to .zip and than unzip it. Which will create a folder and the contents will be same as they were when it was a .egg file
如果您想访问 .egg 文件中的内容，您可以简单地重命名它并将扩展名从 .egg 更改为 .zip，然后解压缩它。这将创建一个文件夹，内容将与 .egg 文件时相同
for example brewer2mpl-1.4.1-py3.6.egg
After Renaming brewer2mpl-1.4.1-py3.6.zip
例如 brewer2mpl-1.4.1-py3.6.egg
重命名brewer2mpl-1.4.1-py3.6.zip 后
Now if we open it, it'll get easily unzipped and the content will be put in a folder with same name in the same directory. (tested on macOS Sierra)
现在，如果我们打开它，它会很容易解压缩，内容将放在同一目录下的同名文件夹中。（在 macOS Sierra 上测试）

just use unzip file.egg this should be enough.
只需使用解压缩 file.egg 这应该就足够了。

Access file from inside egg file
从egg文件中访问文件
Yes, It is possible to read the files from inside egg file.
是的，可以从egg文件中读取文件。
Egg file: mps-1.2.0_M2-py2.6.eggstructure for module level example:
Egg 文件：mps-1.2.0_M2-py2.6.egg模块级结构示例：
In driverfile.py:
在driverfile.py：
import xml.etree.ElementTree
import mps.par.client as syntaxpath
import os
path = os.path.dirname(syntaxpath.__file__)
element = xml.etree.ElementTree.parse(path+'\syntax\syntax.xml').getroot()
print(element)
Read xml file from inside an eggfile:
从eggfile中读取xml文件：
PYTHONPATH=mps-1.2.0_M2-py2.6.egg python driverfile.py
PYTHONPATH=mps-1.2.0_M2-py2.6.egg python driverfile.py

i think by default eggs packing file under python won't add your xml inside to the pack
我认为默认情况下，python 下的鸡蛋打包文件不会将您的 xml 添加到包中
