The reason for your error is that json.loads expects a string, which it then decodes into a python object.错误的原因是json.loads需要一个字符串，然后将其解码为 python 对象。 As a solution, you have two possible options.作为解决方案，您有两种可能的选择。
Option 1选项1
Pass a file object to json.load :将文件对象传递给json.load ：
tweets = json.load(input_file) >>> import json
>>> import pprint
>>> tweets = json.load(open('file.json'))
>>> pprint.pprint(tweets)
