从内存导入pyc？ [英] importing pyc from memory?

问题描述

使用Python / C API，有没有办法可以导入一个内存中的pyc文件（而不是从磁盘加载）？


我正在尝试以专有文件格式保存已编译的python代码，以便在我的应用程序启动时减少编译所有脚本的开销

为什么比在

文件系统上准备好.pyc文件更快？你为什么要用专有的文件格式呢？

你可以使用zip文件作为专有文件格式？使用.pyc'或.py'中的
并将zippath添加到sys.path？


除了你可以加载代码.pyc的对象的内容在一个字符串中

co = marshal.loads（pyc_s [8：]）

mod = imp.new_module（''xy''）

exec co in mod .__ dict__

< blockquote>到目前为止，我已经在XML元素中定义了所有的python脚本，

，这是在我的程序使用Py_CompileString启动时编译的。

这有用太棒了，但我发现大部分时间我的应用程序

用来启动就花在那个Py_CompileString上，因为

大量的脚本我使用。


不幸的是，将这些脚本作为.pyc文件存储在磁盘上并不是我的选择。

Using the Python/C API, is there a way I can import a pyc file that I
have in memory (as opposed to loading from disk)?

I''m trying to save compiled python code in a proprietary file format to
cut reduce the overhead of compiling all my scripts when my app starts
up.

Derek van Vliet enlightened us with:

to cut reduce the overhead of compiling all my scripts when my app
starts up.

Why is that faster than having the .pyc files ready on your
filesystem? And why do you want it in a proprietary file format?

you can use a zip file as "proprietary file format"? with .pyc''s or .py''s in
and add the zippath to sys.path ?

other than that you can load the code object of .pyc''s content in a string
like

co = marshal.loads( pyc_s[8:] )
mod=imp.new_module(''xy'')
exec co in mod.__dict__

Up to now, I''ve had all my python scripts defined in XML elements,
which were compiled when my program started up using Py_CompileString.
This has worked great, but I''m finding that most of the time my app
uses to start up is spent in that Py_CompileString, because of the
large number of scripts that I use.

Unfortunately, storing these scripts as .pyc files on disk is not an
option for me.
