我需要使用 Python 将以下数据写入 yaml 文件:
I need to write the below data to yaml file using Python:
{A:a, B:{C:c, D:d, E:e}}
即字典中的字典.我怎样才能做到这一点?
i.e., dictionary in a dictionary. How can I achieve this?
import yaml
data = dict(
A = 'a',
B = dict(
C = 'c',
D = 'd',
E = 'e',
)
)
with open('data.yml', 'w') as outfile:
yaml.dump(data, outfile, default_flow_style=False)
default_flow_style=False
参数是生成您想要的格式(流样式)所必需的,否则对于嵌套集合,它会生成块样式:
The default_flow_style=False
parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:
A: a
B: {C: c, D: d, E: e}
