首先需要一个Python3环境,怎么准备我就不多说了,实在不会的出门右转看一下廖雪峰老师的博客.
HTML部分代码来自:高德API+Python解决租房问题,简单改了下加载数据部分
代码路径:/static/index.html
Python flask部分毕业生租房 .control-panel { position: absolute; top: 30px; right: 20px; } .control-entry { width: 280px; background-color: rgba(119, 136, 153, 0.8); font-family: fantasy, sans-serif; text-align: left; color: white; overflow: auto; padding: 10px; margin-bottom: 10px; } .control-input { margin-left: 120px; } .control-input input[type="text"] { width: 160px; } .control-panel label { float: left; width: 120px; } #transfer-panel { position: absolute; background-color: white; max-height: 80%; overflow-y: auto; top: 30px; left: 20px; width: 250px; } 公交+地铁 地铁
Python3环境,使用安装Flask,pymysql,BeautifulSoup
pip install Flask;pip install pymysql;pip install beautifulsoup4;pip install requests;
然后直接上代码咯.
路径:/app.py
