利用Python批量修改计算机网络配置

场景是这样的：多台计算机按照楼栋及房间号分配网段及IP地址
初步的方案是人工一间一间房间的去修改，但是这样子非常的繁琐而且慢，所以可以尝试用代码解决这个事情
大致思路：
​ 用字典存储按照楼栋及房间号分配网段及IP地址的信息
​ 用户输入房间号或者用户名，程序执行修改计算机网络配置

import wmi
import time
import subprocess
import os

while True:
    user_name = input("please input the user's name or room number:")
    dic = {"1011": "192.168.235.10"}

    # get computer's cpu
    def get_cpu_info():
        data = {}
        cpu_lists = wmi.WMI().Win32_Processor()
        cpu_core_count = 0
        for cpu in cpu_lists:
            cpu_core_count += cpu.NumberOfCores
            cpu_model = cpu.Name
        data["cpu_count"] = len(cpu_lists)
        data["cpu_model"] = cpu_model
        data["cpu_core_count"] = cpu_core_count
        print("cpu is: " + data.get('cpu_model'))

        if len(adapter) >= 1:

    get_intenet_card()
    get_cpu_info()
    print("***********************************************")
    if user_name not in list(dic.keys()):
        print(
            "*******  this user does not exist, please check again!  *******")
    else:
        fix_adapter(user_name)

    a = input("please input 'exit' to exit this program:")
    if a == 'exit':
        print("*******  successful execution, program exit  *******")
        break

最后可以使用pyinstaller将代码打包为exe文件，并添加图标，如：pyinstaller -F -i xxx.ico fix_information.py
