sudo nano get.py

贴入如下代码：

import os

# Return CPU temperature as a character string                                     

def getCPUtemperature():

    res = os.popen('vcgencmd measure_temp').readline()

    return(res.replace("temp=","").replace("'C\n",""))

# Return RAM information (unit=kb) in a list                                      

# Index 0: total RAM                                                              

# Index 1: used RAM                                                                

# Index 2: free RAM                                                                

def getRAMinfo():

    p = os.popen('free')

    i = 0

    while 1:

        i = i + 1

        line = p.readline()
