文本文件和 json 文件可以互换使用吗？ 如果是这样，我如何在 python 中使用它？

Question

Question: I was wondering if JSON and txt files could be used interchangeably in python.

More Details: I found this on the internet and this on stack overflow to find what a JSON file is but it did not say if json and txt could be used interchangeably ie using the same commands. For example, can both use the same code with open('filename')as file: or does JSON require a different code. Also if they can be used in the same general manner is linking and using commands for a JSON file and a txt file the same process?

Answer 1

A .txt file can contain JSON data, and using open() in Python can open any file, with any content, and any file extension (granted the user running the code has permissions to do so)

It's not until you try to load a non JSON string or file using json.loads or json.load , respectively, where the problem starts.

In other words, a file contains binary data. The data can be represented as a string, that string could be XHTML, JSON, CSV, YAML, whatever, and you must use the appropriate parser to extract the relevant data from that format (but it's not always the file extensions that determine what to use)

does JSON require a different code

It requires another module

import json 
with open(name) as f:
    data = json.load(f) 

Answer 2

You can read the raw data out of any file the same way; the difference is in reading the structure in the data.
