Any complex technology which doesn’t come with documentation must be the best
available.

- 显示引用文字 -需要在python中调用外部程序，比如采用os.system()而所调用的程序的结果直接向终端输出 （比如c里面直接printf）
能否用python直接获取这个值呢？

还是给读者一个例子吧，以免有检测到本邮件的朋友会失望：os.popen()函数会返回一个file对象，读取即可：
>>> import os
>>> command = 'ls'
>>> aa = os.popen(command)
>>> aa
<open file 'ls', mode 'r' at 0xb6ff6d90>
>>> bb = aa.read()
>>> print bb
