import yaml

test.yml文件数据：


yaml_path = r"D:\PycharmProjects\2020study\BBBstudy\test.yml"
with open(yaml_path, 'r') as f:
    cfg = f.read()
    print(cfg)
    # 此时读出来的数据是字符串
    print(type(cfg))
    # 用yaml.load方法转字典
    d = yaml.load(cfg)
    print(d)
    print(type(d))
输出：


# yaml文件写入
file_path = r"D:\PycharmProjects\2020study\BBBstudy\data.yml"
a = {'name': 'chenchen',
     'race': 'Human',
     'traits': ['Two_Hand', 'Two_Eye']
     }
# 写入到yaml文件
with open(file_path, "w", encoding="utf-8") as f:
    yaml.dump(a, f)
