yaml 模块

from typing import *

def yaml_to_dict(file_name:str, encoding='utf8') -> dict:
    import yaml
    with open(file_name, 'r', encoding=encoding) as yaml_f:
        yaml_str = yaml_f.read()
        return yaml.load(yaml_str)

    print_dict(yaml_to_dict(target))

pyyaml 模块

# 直接读取 yam l文件
yaml.load(stream, Loader=yaml.CLoader)

# 保存 yaml 文件
yaml.dump(data, Dumper=yaml.CDumper)

# 带检验的读取 yaml 
yaml.safe_load(stream)
