python获取底层硬件信息

CPU 架构

import platform
print("操作系统名称及版本号:",platform.platform())    #获取操作系统名称及版本号
print("操作系统版本号:",platform.version())           #获取操作系统版本号
print("操作系统的位数:",platform.architecture())      #获取操作系统的位数
print("计算机类型:",platform.machine())               # 计算机类型
print("计算机网络名称：",platform.node())             #计算机网络名称
print("计算机处理器信息:",platform.processor())       #计算机处理器信息
print("上面所有的信息汇总:",platform.uname())         #上面所有的信息汇总

CPU 核数

# 方法一：
# 如果当前Python版本大于2.6，可以简单的通过下面模块来获取当前cpu数量，
import multiprocessing
print("CPU 核数:",multiprocessing.cpu_count())
# 如果是比较老的Python版本，可以用下面的模块来获取当前cpu数量：
import psutil
print("CPU 核数:",psutil.cpu_count())

# 方法二：
# Python可以读系统文件/proc/cpuinfo，过滤“processor”字段统计核心数。
def get_cpu_info():
    processor_cnt = 0
    cpu_model = ""
    f_cpu_info = open("/proc/cpuinfo")
    try:
        for line in f_cpu_info:
#             print(line)
            if (line.find("processor") == 0):
                processor_cnt += 1
        print("cpu counts:{}" .format(processor_cnt))
    finally:
        f_cpu_info.close()
get_cpu_info()

内存信息

# 读取内存信息可以直接读系统文件/proc/meminfo。
def get_mem_info():
    mem_info = ""
    f_mem_info = open("/proc/meminfo")
    try:
        for line in f_mem_info:
#             print(line.strip())
            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()
get_mem_info()

磁盘信息

import os
import subprocess
def get_disc_info():
#     方法一：
    disc_info=os.popen("df -h").read()
    disc_info=subprocess.Popen("df -h",shell=True).communicate()[0]
    print(disc_info)

# 方法二：
#     pipe=subprocess.Popen("df -h",stdout=subprocess.PIPE,shell=True)
#     disc_info=pipe.stdout.read()
#     print(disc_info)
get_disc_info()

网络信息

import netifaces
routingGateway = netifaces.gateways()['default'][netifaces.AF_INET][0] #网关
routingNicName = netifaces.gateways()['default'][netifaces.AF_INET][1] #网络适配器信息
for interface in netifaces.interfaces():
    if interface == routingNicName:
        #print (netifaces.ifaddresses(interface))
        try:
            routingIPAddr = netifaces.ifaddresses(interface)[netifaces.AF_INET][0]['addr'] #获取IP
        except KeyError:
            pass
    #print ("Routing IP Address:%s"% routingIPAddr)
    return routingIPAddr
if __name__ == "__main__":
    try:
        print ("Routing IP Address:",GetNetworkIP())
    except:
        print ("Unable to get the address, there may not be installed netifaces module! command:pip install netifaces")
