выводит ошибку:

Traceback (most recent call last): File "C:\Users\User\PycharmProjects\telegram_bot\main.py", line 11, in from db.methods import * File "C:\Users\User\PycharmProjects\telegram_bot\db\methods.py", line 4, in from base import connection ModuleNotFoundError: No module named 'base'

Сначала код работал в таком виде:

from .base import connection

но почему-то начало выводить ошибку Traceback (most recent call last):

File "C:\Users\User\PycharmProjects\telegram_bot\db\methods.py", line 4, in from .base import connection ImportError: attempted relative import with no known parent package
