exclude of setuptools.find_packages is no use

I set packages in setup.py and doing python3 setup.py sdist bdist_wheel to get whl and tar.gz,

setuptools.setup(
    ...
    packages=setuptools.find_packages(exclude=("ictos_common.tests")),
   ...

then into dist and tar zxf *.tar.gz and find the tests is still here .
so I read the source of setuptools and find something wrong .

class PackageFinder:
    """
    Generate a list of all Python packages found within a directory
    """

    @classmethod
    def find(cls, where='.', exclude=(), include=('*',)):
           return list(cls._find_packages_iter(
                   convert_path(where),
                   # something wrong 
                   # cls._build_filter('ez_setup', '*__pycache__', *exclude),
                      cls._build_filter('ez_setup', '*__pycache__', exclude),
                  # something wrong 
                   cls._build_filter(*include)))

modified like this and tests is gone . so maybe this is a bug .

I see the problem now. You made a typo in constructing tuple literal, e.g. it is ('aaa',) not ('aaa'). I hope that helps.

It is my question,Thank you very much for your reply .
