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这样做：

蟒蛇文件：

 @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] }}

但是这段代码不起作用。它说：

 myList is not defined

我的目的是将多个或更多变量传递给视图。我该怎么办？

我的追溯是：

您不能list用作变量的名称，因为list它是 Python 中的保留关键字。
