touketsu 0.1.1

A package for creating classes that disallow dynamic attribute creation.

touketsu is a tiny package for creating classes that disallow dynamic instance attribute creation or modification while preserving class inheritance. This project was inspired by all the unfortunate incidences where fat-finger errors led to the creation of a new instance attribute instead of the modification of an existing instance attribute.

Installation

On all systems, install the latest version from PyPI with

pip3 install --upgrade touketsu

After installing, check that the package is properly working using the interpreter, for example

>>> from touketsu import immutable
>>> @immutable
... class a_class:
...     def __init__(self, a = "a"):
...         self.a = a
>>> aa = a_class()

Attempting to execute aa.a = 5 will result in an AttributeError, as a_class instances are immutable.
