json.load()从文件中读取json字符串

json.loads()将json字符串转换为字典类型

json.dumps()将python中的字典类型转换为字符串类型

json.dump()将json格式字符串写到文件中

1.json.load()

with open('text.json','r',encoding='utf-8') as f :
print(json.load(f))

{ "name": "anthony", "sex": "man" }

2.json.loads()

#定义字典类型字符串

content = '{"name":"anthony","sex":"man"}'
print type(json.loads(content))
print json.load(content)

<class 'dict'>

{"name":"anthony","sex":"man"}

3.json.dumps()

content = {"name":"anthony","sex":"man"}
print type(json.dumps(content))
print json.dump(content)

<class 'str'>

'{"name":"anthony","sex":"man"}'

4.json.dump()

content = '{"name":"anthony","sex":"man"}'
with open('text.json','w',encoding='utf-8') as f:
json.dump(content,f)

"{ \"name\": \"anthony\", \"sex\": \"man\" }"
