# Dataclass
A **dataclass** is a Python feature that automatically generates common methods (such as `__init__`,` __repr__`, and `__eq__`) for classes that primarily store data. It reduces boilerplate code and makes data models easier to read and maintain.

## Overview
```python
from dataclasses import dataclass

@dataclass(slots=True, frozen=True)
class search_element:
    ...
```

## `slots=True`
Using slots=True creates a fixed set of attributes for each instance instead of a dynamic `__dict__`.

Benefits:
- Reduces memory usage.
- Improves attribute access performance.
- Prevents adding new attributes at runtime.

## `frozen=True`
Using frozen=True makes instances effectively immutable after creation.

Benefits:
- Prevents accidental modification of object state.
- Makes objects safer to share across code.
- Allows instances to be hashable (when appropriate), so they can be used as dictionary keys or stored in sets.
