Question

我是python和flask的初学者。我想将一个列表从.py文件传递给视图文件并执行此操作：

python文件：

 @app.route('/admin',methods=['GET'])

 def panelSettings():   
     myList = ["gan","dalf"]
     return render_template('admin.html',list=myList)

html文件：

my list's first eleman is:{{ list[0] }}

然而这段代码不起作用。它说：

 myList is not defined

我的目的是将多个或多个变量传递给视图。我该怎么办？

我的追溯是：

您不能使用list作为变量的名称，因为list是Python中的保留关键字。

将数组传递给烧瓶中的视图
