Disinherit

This solution involves copying (and caching) the MRO of the class, removing the attributes from each of the copies, and then reassembling the class.

from disinherit import disinherit
from pandas import DataFrame
dataframe = disinherit(DataFrame, '__getattr__')
assert dataframe is not DataFrame
assert dataframe.__new__ is DataFrame.__new__
assert dataframe.__init__ is DataFrame.__init__
assert not hasattr(dataframe, '__getattr__')

Why would you do this?!

I was having problems with pandas.DataFrame.__getattr__, specifically that it exists at all, and could not find a better workaround. Overriding is not an option. In the rare case that someone else has the same problem, I decided to make this solution available. In exchange please smack that star button.

Are you sure?

from pandas import DataFrame

class Test(DataFrame):
    @property
    def foo(self):
        print('foo')
        raise AttributeError

test = Test()
test.foo

foo
foo
Traceback (most recent call last):
  ...
AttributeError

Here you can see that foo is printed twice. This is troublesome for the library that I am working on.

from pandas import DataFrame
from disinherit import disinherit
NoGetter = disinherit(DataFrame, '__getattr__')
class Test(NoGetter):
    @property
    def foo(self):
        print('foo')
        raise AttributeError

test = Test()
test.foo

foo
Traceback (most recent call last):
    ...
AttributeError

Now because __getattr__ is not inherited, there is no problematic recursive behavior.

Installation

I'm not allowed in the PyPI clubhouse yet, so you'll have to install from source:

git clone [email protected]:dhodcz2/disinherit.git
python -m pip install ./disinherit
