求助：如何python中执行下面这个批处理

各位大虾，我打算在python下执行下面这段批处理，为什么每次都返回1，执行失败，求助！
import os
os.system("\"C:\\Program Files\\VMWare\\VMware Workstation\vmrun.exe\" -gu administrator -gp autovm copyFileFromHostToGuest \"C:\\Windows XP Professional SP3 x86\\Windows XP Professional SP3 x86.vmx\" C:\\TAFInstallation\setup.exe C:\\Temp\setup.exe")

补充下，在批处理执行下面这个命令是好用的。

"C:\Program Files\VMWare\VMware Workstation\vmrun.exe" -gu administrator -gp autovm copyFileFromHostToGuest "C:\Windows XP Professional SP3 x86\Windows XP Professional SP3 x86.vmx" C:\TAFInstallation\setup.exe C:\Temp\setup.exe

貌似转义符漏了几个，一律都\\吧免得错，或者加print语句输出命令字串看看...

>>> os.system("\"C:\\Program Files\\VMWare\\VMware Workstation\vmrun.exe\" -gu administrator -gp autovm copyFileFromHostToGuest \"C:\\Windows XP Professional SP3 x86\\Windows XP Professional SP3 x86.vmx\" C:\\TAFInstallation\\setup.exe C:\\Temp\\setup.exe")

>>> 

更新了，还是报错。

>>> print("\"C:\\Program Files\\VMWare\\VMware Workstation\\vmrun.exe\" -gu administrator -gp autovm copyFileFromHostToGuest \"C:\\Windows XP Professional SP3 x86\\Windows XP Professional SP3 x86.vmx\" C:\\TAFInstallation\\setup.exe C:\\Temp\\setup.exe")
"C:\Program Files\VMWare\VMware Workstation\vmrun.exe" -gu administrator -gp autovm copyFileFromHostToGuest "C:\Windows XP Professional SP3 x86\Windows XP Professional SP3 x86.vmx" C:\TAFInstallation\setup.exe C:\Temp\setup.exe
>>> os.system("\"C:\\Program Files\\VMWare\\VMware Workstation\\vmrun.exe\" -gu administrator -gp autovm copyFileFromHostToGuest \"C:\\Windows XP Professional SP3 x86\\Windows XP Professional SP3 x86.vmx\" C:\\TAFInstallation\\setup.exe C:\\Temp\\setup.exe")

打印是对的，不过执行不对。
