dic = {‘k1‘:‘v1‘}
print(type(dic),dic)
import json
str_d = json.dumps(dic)
print(type(str_d),str_d)

dic_d = json.loads(str_d)
print(type(dic_d),dic_d)

結果:

<class ‘dict‘> {‘k1‘: ‘v1‘}
<class ‘str‘> {"k1": "v1"}
<class ‘dict‘> {‘k1‘: ‘v1‘}

-------

import json
dic = {‘k1‘:‘
 
v1‘}
f = open(‘fff‘,‘w‘,encoding=‘UTF-8‘)
json.dump(dic,f)
f.close()

f = open(file = ‘fff‘,mode = ‘r‘,encoding=‘UTF-8‘)
res = json.load(f)
f.close()
print(type(res),res)

結果:

<class ‘dict‘> {‘k1‘: ‘v1‘}

並且生成一個文件,filename為fff,裏面保存了一個dic
