Usage

Decorate your class with constclassattrs and when a class attribute that is uppercase is re-assigned the exception ConstantAssignmentError will be raised.

Example

from constattr.decorators import constclassattrs


@constclassattrs
class Example1:
    MY_CONST1 = '1'
    MY_CONST2 = '2'


# This will raise the ConstAssignmentError exception
Example1.MY_CONST1 = 'new value for the constant'

Limitations

If your class has a metaclass defined, it will work, but in case of conflict the MRO in the metaclass will choose the ConstantEnforcerMeta class first.

Dependencies

This package has no dependencies.
