python处理PHP数组文本文件实例

需求：

对一个配置文件进行处理，拿出可用的字符来拼接，下面是原始文本，我们要得到这样的结果，

redis -h 127.0.0.1 -p 6379 | select 2

redis -h 127.0.0.1 -p 6379 | select 16

redis -h 127.0.0.1 -p 6379 | select 8

原始文本：

    'redis_list' => array(

        'normal' => array(

            'host' => '10.4.3.125',

            'port' => 6405,

            'db' => 6

        ),  

    'redis_list' => array(

        'normal' => array(

            'host' => '127.0.0.1',

            'port' => 6379,

            'db' => 2

        ),  

    'redis_list' => array(

        'normal' => array(

            'host' => '127.0.0.1',

            'port' => 6379,

            'db' => 16

        ),  

    'redis_list' => array(

        'normal' => array(

            'host' => '127.0.0.1',

            'port' => 6379,

            'db' => 8

        ),

上python：

#!/usr/bin/env python

#coding=utf-8

import os
file=open("redis_list.txt", "r")

file_content=file.read()

php_array=file_content.replace("'normal' => array(","")

pstr = php_array.replace(" ","").replace("\r","").replace("\n", "").replace("\t", "").replace("(", "").replace("'", "").replace("),", "")

#print pstr

pstr_list = pstr.split("redis_list=>array")

#print type(pstr_list)
cf_param = []

for i in pstr_list:

 if i:

  ## 'host'=>'127.0.0.1','port'=>6411,'db'=>2

  i_list = i.split(",")

  if len(i_list)==3:

   op = {};

   for ii in i_list:

    ii_list = ii.split("=>")

    if len(ii_list) == 2:

     op[ii_list[0]] = ii_list[1]

   cf_param.append(op)
for i in cf_param:

    print "redis -h "+i["host"] + " -p "+i["port"] +"|select" +" "+i["db"]
