如何在没有语法糖的情况下实例化Python列表

Question

I want to explain object instantiation in Python to some students. They have been coding for a couple of sessions. Now, I'd like to reveal them that they have been working with objects all along. For example, the floats, ints, booleans, lists they have been using are all objects.

Now I want them to show how to instantiate objects. I'd like to show them by using the objects they are already familiar with (eg, lists). But, is there any way to instantiate an empty list very explicitly, eg myList = List() ?

I'm only familiar with syntactic sugar approaches, such as

myList = []

or using the built-in function

myList = list()

Can it be done using the regular instantiation syntax?

Answer 1

Despite the fact that list is writen without the cappital "L", it IS a type in Python. So, when you do the l = list() , you're not calling any built-in function or syntatic suggar, you're instantiating the type list.

The uncapitalized "L" of the list , is the same as the "D" in dict . It's because both are Built-In Types .
