Python For Loop Issues in SmbConnection

Question

I'm trying to move excel files from a network folder to Airflow DAG folder. I am using pysmb and have tested my logic and DAG when connected to a particular file in the network folder, but when i am using for loop to go through the excel files, I am getting errors which don't make sense.

Exception:
unsupported operand type(s) for &: 'int' and 'str'

This is what I am doing.

base_dir = os.path.dirname(os.path.realpath(__file__))
sql_dir = os.path.join(base_dir, 'sql')
staging_dir = os.path.join(base_dir, 'excel_dump')


def pull_file_from_network_share(**kwargs):
     conn = SambaHook.get_connection("CPA")
     pw = conn.get_password()
     print(pw)

     share_name = "cpa"
     user_name = "[email protected]"
     local_machine_name = "lap10"             # arbitrary
     server_machine_name = "boss2b.xyz.com"      # MUST match correctly
     server_IP = "107.21.03.78"        # as must this            

     # create and establish connection
     conn = SMBConnection(user_name, pw, local_machine_name, server_machine_name, use_ntlm_v2 = True)

     conn.connect(server_IP, 139)

     fileList = conn.listPath(share_name,"/SPTS/TaskScheduler/SPE/XYZ/XYZT_RPA/PQR_EU/","*.xlsx")
     # Iterate over the list of filepaths & move each file.
     for filePath in fileList:
         file_obj = tempfile.NamedTemporaryFile(delete=False) 
         csv=os.path.join(staging_dir, filePath)
         file_attributes, filesize = conn.retrieveFile(share_name,  os.path.join(fileList, filePath), file_obj)
         file_obj.close()
         shutil.copy(file_obj.name, csv)
         os.remove(file_obj.name)
