import subprocess
output = str(subprocess.Popen("ntpq -p",shell = True,stdout = subprocess.PIPE, 
stderr = subprocess.STDOUT).communicate()[0])

这是一条直线解

Python 2: http://docs.python.org/2/library/subprocess.html#subprocess.Popen

from subprocess import PIPE, Popen

command = "ntpq -p"
process = Popen(command, stdout=PIPE, stderr=None, shell=True)
output = process.communicate()[0]
print output

在Popen构造函数中，如果shell为True，则应该将命令作为字符串而不是序列传递。否则，只需将命令拆分为一个列表:

command = ["ntpq", "-p"]
process = Popen(command, stdout=PIPE, stderr=None)

如果你还需要读取标准错误到Popen初始化中，你应该将stderr设置为PIPE或STDOUT:

command = "ntpq -p"
process = subprocess.Popen(command, stdout=PIPE, stderr=PIPE, shell=True)
output, error = process.communicate()

注意:从Python 2.7开始，你可以/应该利用subprocess。# subprocess.check_output check_output (https://docs.python.org/2/library/subprocess.html)。

Python 3: https://docs.python.org/3/library/subprocess.html#subprocess.Popen

from subprocess import PIPE, Popen

command = "ntpq -p"
with Popen(command, stdout=PIPE, stderr=None, shell=True) as process:
    output = process.communicate()[0].decode("utf-8")
    print(output)

注意:如果你的目标只是Python版本高于或等于3.5，那么你可以/应该利用subprocess.run (https://docs.python.org/3/library/subprocess.html#subprocess.run)。

这为我重定向stdout工作(stderr可以类似地处理):

from subprocess import Popen, PIPE
pipe = Popen(path, stdout=PIPE)
text = pipe.communicate()[0]

如果它不适合你，请具体说明你的问题。

使用子进程模块的check_output方法

import subprocess

address = '192.168.x.x'
res = subprocess.check_output(['ping', address, '-c', '3'])

最后解析字符串

for line in res.splitlines():

希望能有所帮助，编码愉快

这对我来说非常合适:

import subprocess
try:
    #prints results and merges stdout and std
    result = subprocess.check_output("echo %USERNAME%", stderr=subprocess.STDOUT, shell=True)
    print result
    #causes error and merges stdout and stderr
    result = subprocess.check_output("copy testfds", stderr=subprocess.STDOUT, shell=True)
except subprocess.CalledProcessError, ex: # error code <> 0 
    print "--------error------"
    print ex.cmd
    print ex.message
    print ex.returncode
    print ex.output # contains stdout and stderr together 

import subprocess
output = str(subprocess.Popen("ntpq -p",shell = True,stdout = subprocess.PIPE, 
stderr = subprocess.STDOUT).communicate()[0])
