datatree 0.1.8.1

摘要

DataTree是一个用于在Python中创建结构化文档的DSL。受ruby builder的启发，但旨在减少Python中创建XML文档时相关的行噪声。作为额外的奖励，树可以输出到任何结构化格式（库支持XML、JSON和YAML）。

注意： 更多文档即将推出，但到目前为止，可以在datatree.readthedocs.org找到一个非常基本的草稿。

安装

您可以通过PyPi或直接从github存储库进行安装。

使用pip安装

$ pip install datatree

示例

一个小示例

from datatree import Tree, Node

tree = Tree()
with tree.author() as author:
    author.name('Terry Pratchett')
    author.genre('Fantasy/Comedy')
    author // "Only 2 books listed"
    with author.novels(count=2) as novels:
        novels.novel('Small Gods', year=1992)
        novels.novel('The Fifth Elephant', year=1999)
        novels << Node("novel", "Guards! Guards!", year=1989)

print tree(pretty=True)
