automatic typed collections in python using decorators
Project description
This is a python library for typed containers – it makes it safer & easier to work with lists & dicts of items of the same type by providing:
type checks
container methods
automatic dictionary keys
Example:
import containers @containers.container_class class Item: def __init__(self, x): self.x = x @containers.container_method() def sum(container): return sum(item.x for item in container) @containers.container_key def key(self): return self.x list_ = Item.container(list) list_.append(Item(1)) list_.append(Item(2)) # items of incompatible type are rejected with pytest.raises(TypeError): list_.append(3) # container_method methods are available on the list assert list_.sum() == 3
