yaml的读写

yaml文件的读写是真的快，也很简单。代码如下：

from ruamel.yaml import YAML
import os

# 读取yaml配置文件
def read_yaml(yaml_path):
    yaml = YAML(typ='unsafe')
    try:
        with open(yaml_path, encoding="utf-8") as fp:
            yaml_data = yaml.load(fp)
            fp.close()
            return yaml_data
    except:
        return None


# 写入yaml配置文件
def write_yaml(yaml_path, data, encoding="utf-8"):
    yaml = YAML(typ="rt")
    with open(yaml_path, encoding=encoding, mode="w") as fp:
        yaml.dump(data, stream=fp)
        fp.close()
