List of potential improvements/inclusions

[ES-Alexander]

• f strings (including self-documenting with f'{var=}')
• import this (zen of Python)
• no need to inherit from object (already done implicitly)
• functools.wraps for keeping docstring and metadata for decorated functions
• __class__.__name__ in __repr__ definitions (and __str__ if the name makes sense to display)
• define at least a __repr__, because __str__ falls back on it if undefined
• __repr__ should be unambiguous, __str__ should be readable
• good practice to define a base exception for distributed packages
• copy module copy and deepcopy functions work on arbitrary objects (including custom classes)
• comprehensions are faster and generally more efficient than manual creation
• abs.ABC doesn't allow instantiation of the base class, and raises an error if methods aren't overridden instead of at call time (specifically helpful for instantiable classes, although likely most abstract classes are intended to be instantiable)
• typing.NamedTuple is a memory-efficient shortcut to making immutable classes with a free __repr__ method, named access, and iterability, and reasonably nice definition syntax
• types.SimpleNamespace is a dictionary with dot-accessible keys
• instance properties 'shadow' class properties with the same name (the instance gets asked first, and used unless explicitly called as obj.class.prop)
• factory functions are used to create standard/common instances with different parameters to those normally required (e.g. a VideoWriter from a stream (internal/measurable framerate) instead of from user-generated images)
• make sure @Property is mentioned - setters and getters give actual control over what's accessible to the public interface (although internals are still technically findable/accessible)
• dictionary updates with .update, and creation with defaults {'default': 3, **override}
• tkinter -> tkinter.ttk (more modern and usable widgets)
• underscores in numbers are ignored (can be used for visual separation)
• 3.8 has positional-only and keyword-only arguments (preceded by special arguments '/' and '*') -> raise TypeError if caller specifies a positional only argument as a keyword
• methods defined in a class scope can use class-variables as default values, but can only be used within the method definition if a reference is provided to the class/instance

• Exception wrapping (raise from), as per article and post

• dataclasses
• generators and coroutines
