When using JSON in Python to read a JSON file, an error is reported because the corresponding method is used incorrectly: typeerror: the JSON object must be STR, bytes or byte array, not ‘textiowrapper’.
Solution: first of all, we need to understand that there are four methods for JSON: dumps and loads, dump and load. Among them, dumps and loads are converted in memory (the conversion between Python objects and JSON strings), while dump and load are the processing corresponding to files.
The reason for this error is that I used the loads method to convert the JSON file into a python object, and the correct way is to use the load method.
