我可以使用 zipimport 来发送嵌入式 python 吗?
目前,我正在使用我的应用程序部署完整的 python 发行版(原始 python 2.7 msi)。这是一个用delphi制作的嵌入式Web服务器。
阅读此内容,我想知道是否可能在我的应用程序中嵌入必要的 python 文件,以减少负载文件并避免与多个 python 版本发生冲突。
我以前有过 python for delphi 的经验,所以我只需要知道是否将 python dll + zip 与发行版 + 自己的脚本一起发送即可(如果存在我必须知道的任何警告或我可以查看的示例)
Currently, I'm deploying a full python distribution (the original python 2.7 msi) with my app. Which is an embedded web server made with delphi.
Reading this, I wonder if is possible to embed the necessary python files with my app, to decrease load files and avoid conflict with several python versions.
I have previous experience with python for delphi so I only need to know if only shipping the python dll + zip with the distro + own scripts will work (and if exist any caveats I must know or a sample where I can look)

zipimport
应该适合你——我不熟悉 Delphi 的 Python,但我怀疑它会禁用该功能(嵌入应用程序可以做到这一点,但它是一个不寻常的选择)。请记住,您可以直接压缩并导入的是 Python 编码的模块(或者只是它们相应的.pyc
或.pyo
字节代码)——DLL(即使重命名为.pyd
s;-) 需要在磁盘上加载(因此,如果您有一个 zip 文件,则需要在应用程序启动时将其解压缩,例如解压缩到临时目录中)。此外,您甚至不需要压缩所有模块,只需压缩那些您实际需要的模块(通过传递闭包)——并且您可以轻松地准确找出这些模块是,带有标准 Python 库的 modulefinder 模块。我刚才指出的文档页面上的示例应该可以澄清一些事情。快乐拉链!
zipimport
should work just fine for you -- I'm not familiar with Python for Delphi, but I doubt it disables that functionality (an embedding application can do that, but it's an unusual choice). Just remember that what you can zip up and import directly are the Python-coded modules (or just their corresponding.pyc
or.pyo
byte codes) -- DLLs (even if renamed as.pyd
s;-) need to be on disk to be loaded (so if you have a zipfile with them it will need to be unzipped at the start of the app, e.g. into a temporary directory).Moreover, you don't even need to zip up all modules, just those you actually need (by transitive closure) -- and you can easily find out exactly which modules those are, with the modulefinder module of the standard Python library. The example on the documentation page I just pointed to should clarify things. Happy zipping!
是的,这是可能的。
实际上,我正在使用 Zipimport 库在 Python 中编写自动化脚本。实际上,我在
zip
中包含了每个.py
文件以及这些脚本所需的配置或 xml 文件。然后,我调用一个针对
__main__.py
类的 .command 文件,该文件根据我的sys.argv
参数重定向到所需的脚本,即真的很有用!Yes it is possible.
I'm actually writing automatisation script in Python with the
Zipimport library
. I actually included every.py
files in myzip
as well as configuration or xml files needed by those script.Then, I call a
.command
file targeting a__main__.py
class that redirect towards the desired script according to mysys.argv
parameters which is really useful!
