python shell中怎么重复执行命令

Answer 1

有三种方法：
1、os.system

import os

i = 0

while True:

i = i + 1

os.system("tcpreplay -ibond0 -M 5 -l 1
oracle_request_response.cap")

print"+++++++++++++++++++++++++++++++"

print"times:" ,i

time.sleep(5)

2、os.popen

import os

i = 0

while True:

i = i + 1

print os.popen("tcpreplay -ibond0 -M 5 -l 1
oracle_request_response.cap").read()

print"+++++++++++++++++++++++++++++++"

print"times:" ,i

time.sleep(60)

3、output = Popen("xxx",shell
= True).communicate()[0]

import os

from subprocess import *

i = 0

while True:

i = i + 1

output = Popen("tcpreplay -ibond0 -M 5 -l 1
oracle/*",shell = True).communicate()[0]

print"+++++++++++++++++++++++++++++++"

print"times:" ,i

time.sleep(60)
