使用pyyaml生成具有重写的yaml锚点/引用

import yaml

data = {
    'key1': 'value1',
    'key2': ['item1', 'item2'],
    'key3': {
        'subkey1': 'subvalue1',
        'subkey2': 'subvalue2'
    }
}

yaml_str = yaml.dump(data)

def represent_anchor(dumper, data):
    return dumper.represent_scalar('tag:yaml.org,2002:str', data, style='&')

def represent_reference(dumper, data):
    return dumper.represent_scalar('tag:yaml.org,2002:str', data, style='*')

yaml.add_representer(str, represent_anchor)
yaml.add_representer(str, represent_reference)

yaml_str_with_anchor_reference = yaml.dump(data)

key1: &id001 value1
key2:
- item1
- item2
key3:
  subkey1: subvalue1
  subkey2: subvalue2
