我试过这个:
import os
if os.system('somecommand') == 'output from command':
do_something()
但是没有用。我该怎么做?我应该使用什么库?
当我将解决方案与下面的子流程一起使用时,我得到了这个错误代码:
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.7/subprocess.py", line 537, in check_output
process = Popen(stdout=PIPE, *popenargs, **kwargs)
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
