如何创建CMD进程并向其发送命令

import subprocess

# 创建CMD进程
cmd_process = subprocess.Popen(['cmd.exe'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

# 向CMD进程发送命令
command = 'dir'  # 假设要执行的命令是dir
cmd_process.stdin.write(command.encode('utf-8'))
cmd_process.stdin.write(b'\n')  # 发送换行符以执行命令
cmd_process.stdin.flush()  # 刷新缓冲区确保命令被发送

# 读取CMD进程的输出
output = cmd_process.stdout.read().decode('gbk')  # 假设CMD进程的输出是gbk编码
print(output)
