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\”]
