Générateur de classes Python
Used by developers, writers, and creators worldwide.
A Python class generator gives you a clean class skeleton so you can start coding the logic instead of typing boilerplate. Enter a class name and a comma-separated list of attributes, choose a plain class or a dataclass, and it returns properly indented Python with a docstring, a typed constructor that assigns each attribute, a summary method to fill in, and a readable __repr__ for debugging. The dataclass option swaps all of that for the concise decorator form with typed fields. Developers use it to scaffold a new model quickly, keep a consistent class style, and remember the __repr__ pattern that makes objects printable. It runs in your browser and generates instantly. Paste it into your module, adjust the attribute types from the str default, and flesh out the methods. The structure follows common Python conventions so it reads like code a teammate wrote.

Use Cases
- •Scaffolding a new model or service class quickly
- •Keeping a consistent class style across a codebase
- •Remembering the __init__ and __repr__ boilerplate
- •Choosing between a plain class and a dataclass

- →Keep __repr__ unambiguous so logs are easy to read.
- →Add type hints everywhere so editors can help you.
FAQ
why default the attribute types to str
The generator cannot know your real types, so it uses str as a neutral placeholder that keeps the code valid. Change each annotation to int, float, your own classes, or anything else once you paste it in.
when should I pick the dataclass option
Use a dataclass when the class mainly holds data — it generates the constructor, repr, and equality for you, cutting boilerplate. Choose the plain class when you need custom constructor logic or want full control over each method.
why include a __repr__
A good __repr__ makes objects readable in logs, debuggers, and the REPL, showing the field values instead of an opaque memory address. It is one of the highest-value methods to define and the easiest to forget.
