python subprocess pipe 实时输出日志的操作

* test11.py import timeprint "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()

* 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))
