* test11.pyimport timeprint "1"time.sleep(2)print "1"time.sleep(2)print "1"time.sleep(2)print "1"* t...

* test11.py

import time
print "1"
time.sleep(2)
print "1"
time.sleep(2)
print "1"
time.sleep(2)
print "1"

* test.py

import subprocess

p = subprocess.popen("python test11.py", shell=true, stdout=subprocess.pipe)

# none表示正在执行中

while p.poll() is none: <br>  out = p.stdout.readline() <br>  if out != "": <br>    print out

补充知识:python 通过 subprocess.popen执行命令,重定向实时输出

执行命令

import subprocess
import sys

# 常用编码
gbk = 'gbk'
utf8 = 'utf-8'

# 解码方式,一般 py 文件执行为utf-8 ,cmd 命令为 gbk
current_encoding = gbk
popen = subprocess.popen('ping www.baidu.com', shell = true,
             stdout = subprocess.pipe,
             stderr = subprocess.pipe,
             bufsize = 1)
out,err = popen.communicate()
print('std_out: ' + out)
print('std_err: ' + err)
print('returncode: ' + str(popen.returncode))

执行 .py文件

import subprocess
import sys

# 常用编码
gbk = 'gbk'
utf8 = 'utf-8'

current_encoding = utf8 
popen = subprocess.popen('python d:\code\test.py',
             stdout = subprocess.pipe,
             stderr = subprocess.pipe,
             bufsize = 1)
out,err = popen.communicate()
print('std_out: ' + out)
print('std_err: ' + err)
print('returncode: ' + str(popen.returncode))
