Easily provide python objects with self-identification
Project description
About
Whatami is an attempt to abstract configurability and experiment identifiability in a convenient way.
It works this way:
Objects provide their own ids based on parameters=value dictionaries. They do so by returning an instance of the Configuration class from a method called “what()” (and that’s all)
Optionally, this package provides a Configurable class that can be inherited to provide automatic creation of Configuration objects from the class dictionary (and optionally slots). All attributes will be considered part of the configuration, except for those whose names start or end by ‘_’.
Example
from whatami.config import Configuration, Configurable
# Objects of this class provide a configuration
class DuckedConfigurable(object):
def __init__(self, quantity, name, company=None, verbose=True):
self.quantity = quantity
self.name = name
self.company = company
self.verbose = verbose
def what(self):
return Configuration('ducked', {'quantity': self.quantity, 'name': self.name, 'company': self.company})
duckedc = DuckedConfigurable(33, 'salty-lollypops', verbose=False)
# The configuration id string helps consistency by sorting by key alphanumeric order
print duckedc.what().id()
# u"ducked#company=None#name='salty-lollypops'#quantity=33"
# Inheriting from Configurable makes objects gain a what() method
# In this case, what() is infered automatically
class Company(Configurable):
def __init__(self, name, city, verbose=True):
super(Company, self).__init__()
self.name = name
self.city = city
self._verbose = verbose # not part of config
self.social_reason_ = '%s S.A., %s' % (name, city) # not part of config
cc = Company(name='Chupa Chups', city='Barcelona')
cc.what().id()
u"Company#city='Barcelona'#name='Chupa Chups'"
# We can nest configurations...
duckedc = DuckedConfigurable(33, 'salty-lollypops', company=cc, verbose=False)
print duckedc.what().id()
# ducked#company="Company#city='Barcelona'#name='Chupa Chups'"#name='salty-lollypops'#quantity=33
