# subprocess.run

result = subprocess.run(cmd) # CompletedProcess(args='"', returncode=0) 等待子进程结束

# os.system()

result = os.system(cmd) #子进程的执行结果无法影响主进程，0 等待子进程结束

result = os.system(start "Queueing" cmd.exe /k xx.exe %x%) 启动带标题

# subprocess.Popen()

result = subprocess.Popen(cmd) # <Popen: returncode: None args: ''> 开启子进程

result.pid Popen对象的方法

bat / os.system 从cmd启动x.exe

subprocess / os.system直接调用外部程序x.exe
