问题描述

我正在尝试构建一个常规树。 Python中是否有任何内置的数据结构来实现树?

解决方案

Python没有相当广泛的Java内置的内置数据结构。但是,由于Python是动态的,所以一般的树很容易创建。例如,二叉树可能是:

 类树(对象):
def __init __(self):
self.left =无
self.right =无
self.data =无

您可以这样使用:

  root = Tree()
root.data = root
root.left = Tree()
root.left.data =left
root.right = Tree()
root.right.data =right


I am trying to construct a general tree. Are there any built in data structures in Python to implement a tree?

解决方案

Python doesn't have the quite the extensive range of "built-in" data structures as Java does. However, because Python is dynamic, a general tree is easy to create. For example, a binary tree might be:

class Tree(object):
    def __init__(self):
        self.left = None
        self.right = None
        self.data = None

You can use it like this:

root = Tree()
root.data = "root"
root.left = Tree()
root.left.data = "left"
root.right = Tree()
root.right.data = "right"
