使用正则表达式将文本分割开,然后拼接成应该的格式

转码成 utf-8 输出出来

算是第一次学 Python 吧
学习了下一些基本的语法

#coding:utf-8
# -*- coding: utf-8 -*-
import re
import time
import urllib.request

# 格式
str1="""{% raw %}
<div>
    <div class="oj">   
        <div class="part" title="Description">
{% endraw %}
            $
{% raw %}
        </div>
        <div class="part" title="Input">
{% endraw %}
            $
{% raw %}
        </div>
        <div class="part" title="Output">
