jinja2和模板语言的用法一样
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta http-equiv="content-Type" charset="UTF-8"> <meta http-equiv="x-ua-compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>学生信息</title> </head> <body> {% include "my_block.html" %} {{ stu }} <table border="2px"> <thead> <tr> <th>id</th> <th>name</th> <th>age</th> <th>gender</th> </tr> </thead> <tbody> {% for id,student in stu.items() %} <tr> <td>{{ id }}</td> <td>{{ stu[id].name }}</td> <td>{{ stu.get(id)["age"] }}</td> {% if stu[id]["gender"] != "男" and stu[id]["gender"] != "女" %} <td>女</td> {% else %} <td>{{ stu[id]["gender"] }}</td> {% endif %} </tr> {% endfor %} </tbody> </table> {{ inp}} {{ ab(6,9) }} {{ ab(3,4) | axb(834473503) }} {% macro my_input(na,tp) %} <input type="{{ tp }}" value="{{ na }}"> {% endmacro %} {{ my_input("uname","submit") }} {% block content %} {% endblock %} </body> </html>
