需求：

對一個配置文件進行處理，拿出可用的字符來拼接，下面是原始文本，我們要得到這樣的結果，
代碼如下:
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：

代碼如下:
    '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：

代碼如下:
#!/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]
