Attibute Error: Two methods in a class, one I can reach, the other not (phantom file?

[GaryKuipers]

This is my first post so ... forgive any faux pas.

Error:
AttributeError: 'DatabaseProcess' object has no attribute 'update_card_in_information_from_card_number'

Python3.6 asyncio

This seems straightforward, right? The name must be wrong:

The calling program: Note that the first line causes a problem. If that line is commented the second line succeeeds.

import asyncio
import logging
import json
from Database.database import Database
from Database.database_processes import DatabaseProcess
...
        self.dbprocess = DatabaseProcess(self.log, self.database)
---
        await self.dbprocess.update_card_in_information_from_card_number(request.requestor, request.card_number)
        request.card_record = await self.dbprocess.get_card_record_from_card_number(request.card_number)

Here is the class(callee):

import asyncio
import logging

class DatabaseProcess(object):
    def __init__(self, log, database):
        self.database = database

...
    async def get_card_record_from_card_number(self, card_number):
        stmt = "select * from cards where card_number = '{}' and dt_inactivated is null".format(card_number)

...
    async def update_card_in_information_from_card_number(self, machine_id, card_number):
        exec_stmt = "update cards set dt_last_inserted = now(), last_machine_id = %s where card_number = %s"
...

Here is where it goes bonkers: if I go to the file database_processes.py which contains the DatabaseProcess class and mangle the second name, the one that works, it keeps working.

Aha! we say, must be a duplicate file somewhere in teh path where this class is defined as well ...

It seems not!

grep 'class DatabaseProcess' find / -name 'database*.py'

grep 'a' find . -name 'database*.py'


root@glaptop:/home/.../Database# grep 'class DatabaseProcess' find .../projects/ -name '*.py*'
/home/gary/projects/Brix/Database/database_processes.py:class DatabaseProcess(object):

FINDS IT, that is where I expect it to be. The search starts very high in the directory tree, high enough to find it anywhere.

But this finds nothing in dist-packages (and I wuld not exepct it to becasue this is a dev box)
root@gary-laptop:/home/.../Database# grep 'class DatabaseProcess' find /usr/lib/python3/dist-packages/ -name '*.py*'

What am I missing? Thanks for helpting!
