How to have pyright ignore a method (__getattr__) from it's type checking?

[fzakaria]

I have been creating a proxy class that uses dynamic base hierarchy to pass along the type information like so:

from typing import TYPE_CHECKING, Any

import lief

# Let's make sure type checking works for this proxy class
# https://stackoverflow.com/questions/71365594/how-to-make-a-proxy-object-with-typing-as-underlying-object-in-python
if TYPE_CHECKING:
    base = lief.Binary
else:
    base = object


class Binary(base):
    """Proxy the lief.Binary object to add a path attribute.

    As of https://github.com/lief-project/LIEF/issues/839 the name
    attribute in lief.Binary was removed. Rather than passing around
    a tuple let's create a nice proxy class.
    """

    def __init__(self, path: str):
        self.path = path
        self.__binary = lief.parse(path)

    def __getattr__(self, attr: str) -> Any:
        return getattr(self.__binary, attr)

The problem is that __getattr__ makes anything in Pyright pass and it doesn't do any sensible type checking.
I'd ilke to exclude __getattr__ from it's analysis and have it rely on the types of the base class that I dynamically set based on TYPE_CHECKING.

I have tried # pyright: ignore but that doesn't seem to do anything.

Add if not TYPE_CHECKING to wrap getattr.

if not TYPE_CHECKING:
  def __getattr__(self, attr: str) -> Any:
        return getattr(self.__binary, attr)
