原始代码：
<link rel="icon" href="img/icons/icon-72x72.png">
<link rel="stylesheet" href="style.css">
<link rel="manifest" href="manifest.json">
<img class="big-logo" src="img/core-img/logo-white.png" alt="">
<a class="btn btn-success btn-lg w-100" href="login.html"></a>
<script src="js/jquery.min.js"></script>
结果代码
<link rel="icon" href="{% static 'img/icons/icon-72x72.png' %}">
<link rel="stylesheet" href="{% static 'style.css' %}">
<link rel="manifest" href="{% static 'manifest.json' %}">
<img class="big-logo" src="{% static 'img/core-img/logo-white.png' %}" alt="">
<a class="btn btn-success btn-lg w-100" href="{% static 'login.html' %}"></a>
<script src="{% static 'js/jquery.min.js' %}"></script>
用正则表达式匹配和替换。
t='''<link rel="icon" href="img/icons/icon-72x72.png">
<link rel="stylesheet" href="style.css">
<link rel="manifest" href="manifest.json">
<img class="big-logo" src="img/core-img/logo-white.png" alt="">
<a class="btn btn-success btn-lg w-100" href="login.html"></a>
<script src="js/jquery.min.js"></script>'''
import re
item = re.findall(f'href=\"(.*?)\"', t)+re.findall(f'src=\"(.*?)\"',t)
for x in item:
print(x)
t=re.sub(x,f'{{% {x} %}}',t)
print(t)
上面的大佬基本对了，但是与要求不一致
下面是修改的
import re
item = re.findall(f'href=\"(.*?)\"', t)+re.findall(f'src=\"(.*?)\"',t)
for x in item:
print(x)
t=re.sub(x,f'{{% static \'{x}\' %}}',t)
print(t)
