python擷取系統資訊（系統版本，CPU資訊，記憶體資訊，硬碟資訊）

代碼如下：

import osimport sysimport subprocessdef get_linux_version():        print("system version---- %s" % ", ".join(sys.version.split("\n")))def get_cpu_info():        processor_cnt = 0        cpu_model = ""        f_cpu_info = open("/proc/cpuinfo")        try:                for line in f_cpu_info:                        if (line.find("processor") == 0):                                processor_cnt += 1                        elif (line.find("model name") == 0):                                if (cpu_model == ""):                                        cpu_model = line.split(":")[1].strip()                print("cpu counts: %s, cpu model: %s" % (processor_cnt, cpu_model))        finally:                f_cpu_info.close()def get_mem_info():        mem_info = ""        f_mem_info = open("/proc/meminfo")        try:                for line in f_mem_info:                        if (line.find("MemTotal") == 0):                                mem_info += line.strip()+ ", "                        elif (line.find("SwapTotal") == 0):                                mem_info += line.strip()                                break                print("mem_info---- {:s}".format(mem_info))        finally:                f_mem_info.close()def get_disc_info():        #disc_info = os.popen("df -h").read()        #disc_info = subprocess.Popen("df -h", shell=True).communicate()[0]        #print(disc_info)        pipe = subprocess.Popen("df -h", stdout=subprocess.PIPE, shell=True)        disc_info = pipe.stdout.read()        print(disc_info)

沒有注釋，方法都很簡單，擷取版本是用python內部的sys對象；擷取CPU及記憶體資訊是直接讀/proc下面的檔案，再parse；擷取硬碟資訊則是使用shell命令，再在儲存到python變數中
