我正在尝试将 python 脚本保存到板载 linino RAM，但我无法让它正常工作。我是否正确编写了python脚本文件？谁能查看我的代码并告诉我哪里出错了？我基本上从 arduino 网站上的一个示例中修改了代码以尝试使其工作。我只想写/保存到linino，然后从串口打印输出。提前致谢！
#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);
}

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

Process myscript;

String output = "";
// read the output of the script
while (myscript.available())

// remove the blank spaces at the beginning and the ending of the string
output.trim();
Serial.println(output);
Serial.println("just rand"); //for debugging
