yaml文件读取load()、写入dump()

读取yaml、yml文件：load（）

data=yaml.load(f,Loader=yaml.FullLoader)

要加上：Loader=yaml.FullLoader，否则会报错：YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  data=yaml.load(f)

import yaml

def main():
    with open("./data.yaml","r") as f:
    data=yaml.load(f,Loader=yaml.FullLoader)
    print(data)

if __name__ == '__main__':
    main()

data.yaml文件：

#字典
name: "hello"

运行结果：

 

 

写入：dump（）

data={"S_data":{"test1":"hello"},"Sdata2":{"name":"汉字"}}

encoding='utf-8',allow_unicode=True

#coding=gbk
import yaml

def main():
    #写入数据：
    data={"S_data":{"test1":"hello"},"Sdata2":{"name":"汉字"}}
    with open("./data.yaml","w") as f:
        yaml.dump(data,f,encoding='utf-8',allow_unicode=True)
if __name__ == '__main__':
    main()

data数据中有汉字时，加上：encoding='utf-8',allow_unicode=True

运行结果：

标记：

读取文件时，运行结果：
