复杂控制语句

我们想要显示序号，可以通过loop.index来展示

这里我们想遍历一个复杂的列表字典，可以通过dict.items()，获取到字典的键和值

 实现效果：

 代码实现：

from flask import Flask,render_template



app = Flask(__name__)
student={
    "name":"zhangsan ","age":17,"gender":"男",

}

student_list=[
{
    "name":"zhangsan ","age":17,"gender":"男"},
    {"name":"lisi ","age":25,"gender":"男"},
    {"name":"wangwu ","age":69,"gender":"女"},


]
student_dict=[{

    "aaa":{"name":"zhangsan ","age":17,"gender":"男"},
    "bbb":{"name":"lisi ","age":25,"gender":"男"},
    "ccc":{"name":"wangwu ","age":69,"gender":"女"}
}

]


@app.route('/test1')
def test1():
    return render_template('1.html',**student)

@app.route('/test2')
def test2():
    return render_template('2.html',stu_list=student_list)

@app.route('/test3')
def test3():
    return render_template('3.html',stu_dict=student_dict)


if __name__ == '__main__':
    app.run()
