Language: Python

Severity: Warning

Category: Best Practices

Description

Always define a module once. Do not import the module multiple times and/or import the module using different methods. It makes the code harder to understand. Import a module once and for all with only one import mechanism.

Non-Compliant Code Examples

import logging
import logging  # do not import the same module again.

Compliant Code Examples

import typing
from typing import cast

import logging

import logging
from logging import foo # not an issue since we are using a from import
