C程序可以从命令行工作，但不能从Python脚本工作？

使用整个python脚本更新。

好的，我正在Coursera.org上学习一门机器学习课程，我想看看这些类型的算法可以用加密技术做些什么，并测试一下是否有可能用神经网络来破解加密。首先，我需要为一个训练集创建一个哈希表，但在C字符串数组、args和Python将字符串作为args传递给C程序时遇到了问题

这是我的lilc程序hashpipe

    #include <stdio.h>
    #define __USE_GNU
    #include <crypt.h>
    #include <string.h>

    int main(int argc, char** argv){
            char * salt = argv[2];
            struct crypt_data data;
            data.initialized = 0;
            char * result = crypt_r(argv[1], id, &data);
            printf("%s\n", result);
            return 0 // This was the bugger!!! I forgot it!!!
    }

我一直在对这部分进行大量更改，但没有任何效果，这是怎么回事？它可以在命令行上工作，但不能在python中工作。例如，

strip（'\0'）

和

str（r“$”）

是我最近做的一些修改，但仍然不起作用。也许我会写一个bash脚本来代替

请注意，编译的C程序在cmd行上执行它应该执行的操作。

DOH！

我需要在我的C程序中返回0。现在工作只是为了让你知道。创建我的第一个排序哈希表：）

请提供示例输入，以使Python示例重现。
