yaml多嵌套和python字典
[英]yaml multi nested and python dictionary
问题描述
I am new to yaml the output is in the expected format but wondering if there is a better way to construct the below nested objects in yaml. 
我是yaml的新手，输出是预期的格式，但想知道是否有更好的方法在yaml中构造下面的嵌套对象。
import yaml
yaml.load ("""

I can think of two ways that will save you some typing on the yaml front. 我可以想到两种方法可以节省你在yaml前面的打字。
Use the short mapping syntax: 使用短映射语法：
test1:
a:
a1:
a2: {a3: 0, b3: 0, c3: 0}
b2: {a3: 0, b3: 0, c3: 0}
c2: {a3: 0, b3: 0, c3: 0}
b1:
a2: {a3: 0, b3: 0, c3: 0}
b2: {a3: 0, b3: 0, c3: 0}
c2: {a3: 0, b3: 0, c3: 0}
c1:
a2: {a3: 0, b3: 0}
Use aliases: 使用别名：
entry: &aliasentry
a2: {a3: 0, b3: 0, c3: 0}
b2: {a3: 0, b3: 0, c3: 0}
c2: {a3: 0, b3: 0, c3: 0}
test1:
a:
a1: *aliasentry
b1: *aliasentry
c1: {a2: {a3: 0, b3: 0}}
