You might not need a Python class

- Python's built-in types, functions, and standard library modules can often provide simpler alternatives to classes.
- For simple data containers, named tuples or data classes (Python 3.7+) are cleaner and more concise than classes.
- Stateless utility functions can be implemented as standalone functions instead of class methods.
- Grouping constants is better handled by modules rather than classes.
- Simple state management can often be achieved with dictionaries or lists instead of classes.
- One-off operations can be simplified using lambdas or comprehensions instead of class methods.
- Python's extensive standard library should be checked before writing custom classes.
- Classes are useful for encapsulating state and behavior, modeling complex structures, and when objects have clear behavior associated with their data.
- Before writing a class, consider if built-ins, standard libraries, or simpler techniques can achieve the same goal more efficiently.
