在Python脚本中嵌入泡菜（或任意）数据 [英] Embed pickle (or arbitrary) data in python script

问题描述

在Perl中，解释器在遇到以下一行时就会停止

In Perl, the interpreter kind of stops when it encounters a line with

__END__

其中。这通常用于在perl脚本的末尾嵌入任意数据。这样，perl脚本可以获取并存储自身存储的数据，这提供了很好的机会。

in it. This is often used to embed arbitrary data at the end of a perl script. In this way the perl script can fetch and store data that it stores 'in itself', which allows for quite nice opportunities.

在我的情况下，我有一个腌制的对象我想存放在某个地方。虽然我可以很好地使用file.pickle文件，但我正在寻找一种更紧凑的方法（以便更轻松地分发脚本）。

In my case I have a pickled object that I want to store somewhere. While I can use a file.pickle file just fine, I was looking for a more compact approach (to distribute the script more easily).

有没有一种机制可以允许

Is there a mechanism that allows for embedding arbitrary data inside a python script somehow?

推荐答案

如果数据不是特别大（很多K），我会这样做。将其编码（'base64'）并将其包含在三引号引起来的字符串中，并使用.decode（'base64'）取回二进制数据，并在其周围进行pickle.loads（）调用。

If the data is not particularly large (many K) I would just .encode('base64') it and include that in a triple-quoted string, with .decode('base64') to get back the binary data, and a pickle.loads() call around it.
