tornado与django、flask的5点区别:
 
①改了后台代码后不自动重新运行,要点击运行窗口的Rerun;
②运行窗口不自动显示127.0.0.1:端口号,可print一个,或在浏览器地址栏手输;
③最新版的PyCharm,New Project列表中,目前仍无自动创建tornado的模板;
④Python文件,默认和html文件在同个目录下,或在路由的后面指定templates和static文件夹。
⑤html模板中:字典用d['key'],而非d.key;判断和循环的结尾,都是{% end %},而另俩web框架则是用{% endif %}、{% endfor %}、{% endwith %}
