在python中从文件读取C结构

Question

I have very little experience with C, so I apologize in advance if something I say does not make sense.

I am working on a project in which my entire base of code is written in python 2.7. I am at a point where I must read in data created by someone else who is using C. Each data file he has given me consists of a header struct, such as...

struct Header {
    int32_t x1;
    int32_t x2;
    .
    .
    .
};

This is then followed by an array of structs of identical format, each containing data for a single element in a simulation.

Is there a way to read this data in with python? It seems like I need to use python's struct module, but I've read through the documentation and either I can't find what I need or don't understand how I should use it.

Thank you!

看一下struct模块的pack ＆ unpack函数或ctypes模块-要么可以将您整理出来，但最好取决于几个因素， numpy还包括用于读取“外来”数据的函数，可以提供帮助。
