Effective constant management tools

Const-Utils

const-utils is a small-yet-effective library that offers some tools for working with Python constants. Its main feature is the Constant Class, which includes utilities for accessing constants, stored within a container class.

Defining constant classes is available by using ConstClassMeta (as a metaclass), or the standard BaseConstClass (by inheritance).

Examples

Creating a constant class

class CountryConsts(BaseConstClass):
    US = 'United States of America'
    UK = 'United Kingdom'

Access options

Access from the class itself

>>> CountryConsts.as_dict()  # {'US': 'United States of America', 'UK': 'United Kingdom'}
>>> CountryConsts['US']  # 'United States of America
>>> Country.const_names  # ['US, 'UK']
>>> Country.const_values  # ['United States of America', 'United Kingdom']

Access global/local constants

>>> # Access current global/local constants (depends on kwarg `local`)
>>> # as a dictionary of names to values
>>> access_namespace_consts(local=False)

Storing class constants to a namespace

>>> # Store constants in a module
>>> CountryConsts.apply_to_module('some_module_name', override=True)
>>> # Store constants as globals
>>> CountryConsts.apply()
>>> # Store constants as locals
>>> CountryConsts.apply(local=True)
