Create a list of default objects of a class in Python?

Question

I have define a class in Python

class node(object):
    def __init__(self, children = []):
        self.children = children

I would like to create a list or array of default objects of class node. For example, something like in C++

node * nodes = node[100];

then nodes will point to an array of 100 default objects of class node.

How is it done similarly in Python? Thanks.

Answer 1

Using a list comprehension:

nodes = [node() for _ in range(100)]

Answer 2

You can use a list comprehension:

nodes = [node() for _ in range(100)]

Python doesn't have a concept of "arrays" per se, but it has lists which are a higher-level structure. Lists can be indexed just like C arrays, and support many more complex operations.
