Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
Expand functools features to methods, classmethods, staticmethods and even for (unofficial) hybrid methods.
For now, methodtools only provides methodtools.lru_cache
.
Use methodtools
module instead of functools
module. Than it will work as
you expected.
.. code:: python
from methodtools import lru_cache
class A(object):
# cached method. the storage lifetime follows `self` object
@lru_cache()
def cached_method(self, args):
...
# cached classmethod. the storage lifetime follows `A` class
@lru_cache() # the order is important!
@classmethod # always lru_cache on top of classmethod
def cached_classmethod(self, args):
...
# cached staticmethod. the storage lifetime follows `A` class
@lru_cache() # the order is important!
@staticmethod # always lru_cache on top of staticmethod
def cached_staticmethod(self, args):
...
@lru_cache() # just same as functools.lru_cache
def cached_function():
...
PyPI is the recommended way.
.. sourcecode:: shell
$ pip install methodtools
