flask实现json数据处理、学生信息表格展示和jinjia2的用法

from flask import Flask, render_template
STUDENT = {'name': 'Old', 'age': 38, 'gender': '中'}
STUDENT_LIST = [
    {'name': 'Old', 'age': 38, 'gender': '中'},
    {'name': 'Boy', 'age': 73, 'gender': '男'},
    {'name': 'EDU', 'age': 84, 'gender': '女'}
]
STUDENT_DICT = {
    1: {'name': 'Old', 'age': 38, 'gender': '中'},
    2: {'name': 'Boy', 'age': 73, 'gender': '男'},
    3: {'name': 'EDU', 'age': 84, 'gender': '女'},
}
app = Flask(__name__)
app.debug = True
@app.template_global()
def ab(a, b):
    return a + b
@app.route("/stu")
def stu():
    return render_template("stuinfo.html", stu_info=STUDENT, stu_list=STUDENT_LIST, stu_dict=STUDENT_DICT)
if __name__ == '__main__':
    app.run("0.0.0.0", 9527)
用到的html页面

  


{{ stu_info }}











  
    
name
    
age
    
gender
  
  
    
{{ stu_info.name }}
    
{{ stu_info.get("age") }}
    
{{ stu_info["gender"] }}
  
{{ stu_list }}






  {% for stu in stu_list %}





  {% endfor %}
  
    
name
    
age
    
gender
  
    
      
{{ stu.name }}
      
{{ stu.get("age") }}
      

        {% if  stu["gender"] != "男" and stu["gender"] != "女" %}
          李杰
        {% else %}
          {{ stu["gender"] }}
        {% endif %}
      
    
{{ stu_dict }}
{% for foo in stu_dict %}
  {{ stu_dict[foo].get("name") }}
  {{ stu_dict[foo]["age"] }}
  {{ stu_dict[foo].gender }}
{% endfor %}
{% for foo,item in stu_dict.items() %}
  {{ foo }}
  {{ item.name }}
{% endfor %}
{{ ab(666,2) }}
{% macro my_input(ty,na) %}
  请输入用户名 -> 
{% endmacro %}
这就是我自己创造的input标签：{{ my_input("text","username") }} {{ my_input("password","pass") }} {{ my_input("file","myfile") }}
