+ # 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.
