json.dumps和 和有json.load什么区别？
From my understanding, one loads JSON into a dictionary and another loads into objects.
根据我的理解，一个将 JSON 加载到字典中，另一个加载到对象中。

dumpstakes an object and produces a string:
dumps接受一个对象并产生一个字符串：
>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'
loadwould take a file-like object, read the data from that object, and use that string to create an object:
load将获取一个类似文件的对象，从该对象读取数据，并使用该字符串创建一个对象：
with open('file.json') as fh:
a = json.load(fh)
Note that dumpand loadconvert between files and objects, while dumpsand loadsconvert between stringsand objects. You can think of the s-less functions as wrappers around the sfunctions:
注意dumpandload在文件和对象之间转换，而dumpsandloads在字符串和对象之间转换。您可以将s-less 函数视为函数的包装器s：
def dump(obj, fh):
fh.write(dumps(obj))
def load(fh):
return loads(fh.read())

json loads -> returns an object from a string representing a json object.
json 加载 -> 从表示 json 对象的字符串返回一个对象。
json dumps -> returns a string representing a json object from an object.
json dumps -> 从对象返回一个表示 json 对象的字符串。
load and dump -> read/write from/to file instead of string
加载和转储 -> 读取/写入文件而不是字符串
