I wrote the below code

    def fin_remove_additional_folders():
        if os.path.exists(u'inputpizz\xe4'):
            utils.rmtree(u'inputpizz\xe4')
        if os.path.exists(u'inputgreen'):
            utils.rmtree(u'inputgreen')
        if os.path.exists(u'inputbinary_files'):
            utils.rmtree(u'inputbinary_files')
        if os.path.exists(u'tests/custom_output_dir'):
            utils.rmtree(u'tests/custom_output_dir')
        if os.path.exists(u'inputpermissions'):
            utils.rmtree(u'inputpermissions')
    request.addfinalizer(fin_remove_additional_folders)
