使用 Python 生成 YAML 时防止长文本换行

Question

我正在尝试生成类似于以下格式的 YAML：

version: '3.1'
nlu:
- intent: anxiety_intent
  examples: |
    - my anxiety has been overwhelming lately.
    - i am struggling with my stress levels right now.
    - i'm having a bit of a crisis and not serious, but need to talk just a very long panic attack.

到目前为止，我能够生成如下 YAML：

version: '3.1'
nlu:
- intent: anxiety_intent
  examples: |
    - my anxiety has been overwhelming lately.
    - i am struggling with my stress levels right now.
    - my anxiety has been bad.
    - i'm having a bit of a crisis and not serious, but need to talk just a very long
      panic attack.

如您所见，最后一句话很长，被换行到下一行。我怎样才能防止这种情况发生？

我从那里提取数据的谷歌表格。示例如下所示：

到目前为止，这是我的方法：

import yaml
from yaml.resolver import BaseResolver

class AsLiteral(str):
  pass

def represent_literal(dumper, data):
  return dumper.represent_scalar(BaseResolver.DEFAULT_SCALAR_TAG, data, style="|")

yaml.add_representer(AsLiteral, represent_literal)

def generate_intent_dict(worksheet):
    rows = worksheet.get_all_records()
    df = pd.DataFrame(rows)
    all_intent_list = {col : [x for x in df[col].values if x != ''] for col in df}
    filtered_intent_list = {k: v for k, v in all_intent_list.items() if v}
    return filtered_intent_list

def generate_yaml_specific_intent_dict(intents_dict):
    yaml_dict = {
        "version" : "3.1",
        "nlu" : [
        ],
    }

    for k, val in intents_dict.items():
        d1 = dict()
        d1['intent'] = k 

        info_str = AsLiteral(yaml.dump(val))
        d1['examples'] = info_str
        yaml_dict['nlu'].append(d1)
    return yaml_dict

def yaml_specific_intent_write(yaml_dict, path, fname):
    with open(os.path.abspath(path + fname), 'w') as f:
        yaml.dump(yaml_dict, f, sort_keys=False)

我尝试了很多东西，但都无济于事。我猜 YAML 转储存在一些问题。任何帮助将不胜感激。
