Learn How to Use JSON as a Small Database for Your Py Projects by Building a Hotel Accounting System
u/RevolutionaryAd8906 , I appreciate your good intentions in creating a beginner-friendly tutorial like this. JSON is a core technology that anyone working with modern APIs should understand, and it's important to make learning accessible for beginners. That said, your mindset of setting up JSON to be thought of as a "database" is perhaps sub-optimal ... while it's useful to teach data persistence early on, positioning JSON as a database can set beginners up for struggles down the line. I think you know this, and I see where you're going with it, but fundamentally it sets up a paradigm in the heads of new programmers that is misaligned with best practices. JSON files are easy to use and understand, making them great for small projects or single-user applications. Maybe a to-do list or managing simple configuration settings, storing user preferences, tracking small collections (e.g., book or movie lists). JSON works well if the scale is very limited. The progression from using JSON for data storage to interacting with APIs is logical and effective. However the limitations of JSON are very quickly apparent: Scalability: JSON is not designed for large datasets (like managing a hotel............. maybe suggest a different example in your HOW TO?) Performance degrades significantly with thousands of records, as the entire file must be read and written each time. RAM also becomes a limiting factor. Beyond a few thousand records, load and save times will noticeably degrade, especially with detailed records. Concurrency: JSON does not handle concurrent access. When multiple users or processes interact with the data, conflicts and errors are likely. Traditional databases manage this with record locking, transactions, and ACID compliance. Data Integrity and Security: JSON lacks built-in features for enforcing data types, constraints, or relationships. Storing sensitive information in plain-text JSON without encryption is risky (like the hotel guests credit card numbers and addresses...??) Databases like SQLite or even NoSQL options like MongoDB help mitigate these issues. Integrating databases from the beginning with new programming students can be valuable and I would argue worth doing. It seems to me you're kicking a can down the line and instilling a bad notion in their heads that they can use JSON as a flat file database. SQLite, for instance, requires minimal setup and offers skills that are more transferable to complex projects. It introduces concepts like relationships, querying, and data normalization, which can save a lot of headaches later on. I wonder if there's a middle ground where you introduce data persistence with JSON, and then transition to something like SQLite or an ORM in short order? This would help beginners avoid the pitfalls of using JSON beyond its intended use while still learning important concepts in a manageable way. Anyway ... not trying to criticize too harshly, but I think this is a misguided way to teach what JSON is all about. More on reddit.com

Working with JSON in Python
Nice article. One minor, super-pedantic nit-pick: you keep using the words "JSON object", when you don't really mean that. A "JSON object" is merely one particular type a JSON string or text can hold, as defined by RFC7159 and its update RFC8259 , ECMA262 , ECMA404 , W3C, and various other standards. So you keep describing how to convert to/from "JSON object", when what you're really doing is converting to/from JSON string (which are also python strings) - and those strings actually are of JSON arrays in your examples, not JSON objects. The arrays happen to contain JSON objects inside the array. So for example this: json.dumps() takes in a Python data type and returns a JSON object. json.loads() takes in a JSON object and returns a Python data type. ...isn't actually true. For example just the two characters 42 is a perfectly valid JSON string, of just a JSON number type. Python's json.dumps() will accept a python int of 42 and convert it to a string. It will then take that serialized python/JSON string and convert it back to a simple python int, using json.loads(). There is no JSON object involved whatsoever. Again, I know I'm being pedantic. And I don't mean to criticize - the article's fine overall. I just get triggered by some minor details sometimes. :) More on reddit.com

Simple tutorials for using reddit api in Python?
Using an API just comes down to making a request to the right end-point (e.g. /api/v1/me), which then returns data. Most of the time this data is in either JSON or XML format.
Now in order to view that end-point (/api/v1/me) you need to be authenticated via OAuth, which is a whole separate process. (But also including making requests by sending the right data back and forth.)
Now to make it easy, you can just use PRAW. Which has a small tutorial on their website. :)
August 20, 2025 - Its syntax resembles Python ... lowercase for Boolean values. With built-in tools for validating syntax and manipulating JSON files, Python makes it straightforward to work with JSON data. By the end of this tutorial, youโll understand that:...
December 3, 2024 - Learn how to work with JSON in Python, including serialization, deserialization, formatting, optimizing performance, handling APIs, and understanding JSONโs limitations and alternatives.
The json module provides functions to work with JSON data, allowing you to serialize Python objects into JSON strings and deserialize JSON strings back into Python objects. JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is mainly used to transmit data between a server and web application as text. JSON serialization is the process of converting a Python object into a JSON format.
In this tutorial, we'll see how we can create, manipulate, and parse JSON in Python using the standard a json module. The built-in Python json module provides us with methods and classes that are used to parse and manipulate JSON in Python. JSON (an acronym for JavaScript Object Notation) is ...
December 23, 2025 - Perform additional JSON operations in Python, including formatting, pretty-printing, flattening nested objects, validating JSON strings, and sorting JSON data by values.
June 5, 2023 - It is named JSON because it closely mimics the syntax used in JavaScript objects. In this tutorial, you will explore the JSON module in Python and learn how to effectively work with JSON data.
In this tutorial, you will learn to parse, read and write JSON in Python with the help of examples. Also, you will learn to convert JSON to dict and pretty print it.
March 9, 2023 - Python for Beginners: How to Use JSON in Python ยท tutorial, Data / Python / Software Development ยท How to parse JSON files within a Python program. May 1st, 2022 5:00am by Jack Wallen ยท JSON is an outstanding way of storing and transferring data.
1 month ago -Using Python's context manager, create a file named Sample.json and open it with write mode. Here, the dump() takes two arguments first, the data object to be serialized and second the object to which it will be written(Byte format).
Encoding a custom object with the default JSONEncoder will raise a TypeError. We can specify a custom encoding function that will store the class name and all object variables in a dictionary.
