你好，我有这个Yaml文件
host_image:
host_flavor:
host_key_private:
host_key_public:
并且，鉴于所有的字符串值，我都希望以此yaml结尾
host_image: 8da0966a-dc3b-4501-b35e-26aa3c210bf7
host_flavor: 2
host_key_private: |

我仅对host_key_private有一个问题，因为我知道它太长了，但是我不知道如何用块编写。我的脚本是这个
import yaml
# edit input file adding node's inputs
with open(yamlFile) as f:
doc = yaml.safe_load(f)
doc['host_flavor'] = host_flavor
doc['host_image'] = host_image
doc['host_key_private'] = host_key_private
with open(yamlFile, 'w') as f:
yaml.dump(doc, f)
我得到的是这个：
host_flavor: 2
host_image: 8da0966a-dc3b-4501-b35e-26aa3c210bf7
