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，
复制代码 代码如下:
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：

复制代码 代码如下:
    '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：

复制代码 代码如下:
#!/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"]
