import os   
 list = os.popen('pwd').read()

在这种情况下，列表中只有一个元素。

对于python 3.5，我根据前面的回答提出了函数。原木可能被移除，但它很好

import shlex
from subprocess import check_output, CalledProcessError, STDOUT


def cmdline(command):
    log("cmdline:{}".format(command))
    cmdArr = shlex.split(command)
    try:
        output = check_output(cmdArr,  stderr=STDOUT).decode()
        log("Success:{}".format(output))
    except (CalledProcessError) as e:
        output = e.output.decode()
        log("Fail:{}".format(output))
    except (Exception) as e:
        output = str(e);
        log("Fail:{}".format(e))
    return str(output)


def log(msg):
    msg = str(msg)
    d_date = datetime.datetime.now()
    now = str(d_date.strftime("%Y-%m-%d %H:%M:%S"))
    print(now + " " + msg)
    if ("LOG_FILE" in globals()):
        with open(LOG_FILE, "a") as myfile:
            myfile.write(now + " " + msg + "\n")

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 

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

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
