功能是指定程序关闭后自动重启，并点击1作为启动
原来的想法是群成员说的某软件打包后，软件进程被杀后，界面白屏。所以写了个计算器重启demo进行进程守护

import subprocess
import time
import pyautogui
import psutil
#用计算器做演示。
def is_calculator_running():
    # 查找所有正在运行的计算器进程
    for proc in psutil.process_iter(['pid', 'name']):
        # 检查进程名是否为 'Calculator.exe'
        if proc.info['name'] == 'Calculator.exe':
            return True
    return False

def open_calculator():
    # 启动计算器进程
    process = subprocess.Popen('calc.exe')
    return process

def click_button_1():
    # 等待计算器打开并加载
    time.sleep(2)  # 根据需要调整等待时间

    # 模拟点击"1"按钮，这里直接发送"1"键
    # 注意：确保计算器是当前激活的窗口
    pyautogui.press('1')

def main():
    while True:
        if not is_calculator_running():
            print("Calculator is not running. Starting...")
            process = open_calculator()
            click_button_1()
        time.sleep(1)  # 每秒检查一次

if __name__ == '__main__':
    main()
