将Python脚本写入并保存到Arduino Yun的RAM中

Question

我正在尝试把一个Python脚本保存到Linino的内存里，但总是搞不定。请问我写的Python脚本文件正确吗？有没有人能看看我的代码，告诉我哪里出错了？
我基本上是根据Arduino网站上的一个例子修改的代码，想让它能正常工作。我只是想把数据写入Linino，然后从串口打印输出。
提前谢谢大家！

#include <FileIO.h>

void setup() {
// Setup Bridge (needed every time we communicate with the Arduino Yún)
Bridge.begin();
// Initialize the Serial
Serial.begin(9600);

while(!Serial);  // wait for Serial port to connect.
Serial.println("File Write Script example\n\n");

// Setup File IO
FileSystem.begin();

// Upload script used to gain network statistics  
uploadScript();
}  

void loop() 
{
// Run stats script every 5 secs.
runScript();
Serial.println("Just ran script");
delay(5000);
}

// this function creates a file into the linux processor
void uploadScript() 
{
// Write our shell script in /tmp
// Using /tmp stores the script in RAM this way we can preserve 
// the limited amount of FLASH erase/write cycles
File script = FileSystem.open("/tmp/example.py", FILE_WRITE);
script.print("#!/usr/bin/python");
script.print("import urllib2");
script.print("import ast");
script.print("r = urllib2.urlopen('https://python.org')");
script.print("a = r.read()");
//script.print("y = ast.literal_eval(a)");
script.print("print a[:100]"); //i want to index something in the dictionary
script.close();  // close the file

// Make the script executable
Process chmod;
chmod.begin("chmod");      // chmod: change mode
chmod.addParameter("+x");  // x stays for executable
chmod.addParameter("/tmp/example.py");  // path to the file to make it executable
chmod.run();
}


// this function run the script and read the output data
void runScript() 
{
// Run the script and show results on the Serial
Process myscript;
myscript.begin("/tmp/example.py");
myscript.run();

String output = "";

// read the output of the script
while (myscript.available()) 
{
  output += (char)myscript.read();
}
// remove the blank spaces at the beginning and the ending of the string
output.trim();
Serial.println(output);
Serial.println("just rand"); //for debugging
Serial.flush();
}

大约一年前，我刚开始接触这个问题的时候，还是个新手。现在回想起来，直接通过SSH连接到Arduino，然后在vi编辑器里写脚本并保存到Yun的Linux系统上，确实简单多了。我这样做没有遇到任何问题，脚本运行得也很好。别费劲在Arduino的草图里写Linux的脚本了！祝好。
