如何在使用subprocess.Popen的同时设置输出文件，同时隐藏命令窗口？

import subprocess

# 创建输出文件对象
output_file = open('output.txt', 'w')

# 设置subprocess.Popen的参数
process = subprocess.Popen(['command', 'arg1', 'arg2'], stdout=output_file)

# 等待命令执行完成
process.wait()

# 关闭输出文件
output_file.close()

import subprocess

# 创建启动信息对象
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = subprocess.SW_HIDE

# 设置subprocess.Popen的参数
process = subprocess.Popen(['command', 'arg1', 'arg2'], startupinfo=startupinfo)

# 等待命令执行完成
process.wait()

import subprocess

# 创建输出文件对象
output_file = open('output.txt', 'w')

# 创建启动信息对象
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = subprocess.SW_HIDE

# 设置subprocess.Popen的参数
process = subprocess.Popen(['command', 'arg1', 'arg2'], stdout=output_file, startupinfo=startupinfo)

# 等待命令执行完成

# 关闭输出文件
output_file.close()
