本篇文章為大家展示了python Yaml、Json、Dict之間如何進行轉化，內容簡明扼要并且容易理解，絕對能使你眼前一亮，通過這篇文章的詳細介紹希望你能有所收獲。
Json To Dict
import json
jsonData = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
print(jsonData)
print(type(jsonData))
text = json.loads(jsonData)
print(text)
print(type(text))

<class 'str'>
{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
<class 'dict'>Dict To Json
import json
textDict = {"a":1,"b":2,"c":3,"d":4,"e":5}
print(textDict)
print(type(textDict))
# 字典轉化為json
textJson = json.dumps(textDict)
print(textJson)
print(type(textJson))

<class 'dict'>關于 yaml -> dict 需要注意
yaml 5.1版本后棄用了yaml.load(file)這個用法，因為覺得很不安全，5.1版本之后就修改了需要指定Loader，通過默認加載​​器（FullLoader）禁止執行任意函數

/Users/yyj/Desktop/Project/HelloBike/TimeCalc/pydict2json/dict2json.py:88: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
dictText = yaml.load(yamlText)

<class 'dict'>1、警告提示
YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default
Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
2.主要原因
yaml 5.1版本后棄用了yaml.load(file)這個用法，因為覺得很不安全，5.1版本之后就修改了需要指定Loader，通過默認加載​​器（FullLoader）禁止執行任意函數
3.解決方法
1.yaml.load(f, Loader=yaml.FullLoader)
2.yaml.warnings({'YAMLLoadWarning': False}) # 全局設置警告，不推薦
Loader的幾種加載方式
