需要帮助使用 python 创建复杂的 yaml

Question

我有以下代码

name = "testyaml"
version = "2.5"
os = "Linux"
sources = [
     {
          'source': 'news', 
          'target': 'industry'
     }, 
     {
          'source': 'testing', 
          'target': 'computer'
     }
]

我想用 python3 制作这个 yaml

services:
   name: name,
   version: version,
   operating_system: os,
   sources:
     -
      source: news
      target: industry
     -
      source: testing
      target: computer

我需要一个关于 Sources 部分的帮助，我可以在那里添加我的字典列表

Answer 1

import yaml

name = "testyaml"
version = "2.5"
os = "Linux"
sources = [
    {"source": "news", "target": "industry"},
    {"source": "testing", "target": "computer"},
]

yaml.dump(
    {"services": {"name": name, "version": version, "os": os, "sources": sources}}
)

Answer 2

Python 的yaml 模块允许您将字典数据转储为 yaml 格式：

import yaml

# Create a dictionary with your data
tmp_data = dict(
    services=dict(
        name=name,
        version=version,
        os=os,
        sources=sources
    )
)

if __name__ == '__main__':
    with open('my_yaml.yaml', 'w') as f:
        yaml.dump(tmp_data, f)

来自 yaml 的内容：

services:
  name: testyaml
  os: Linux
  sources:
  - source: news
    target: industry
  - source: testing
    target: computer
  version: '2.5'
