Key python.logging.print-instead-of-logger · Severity info · Category logging

Writing to the console with print lacks configurable features like log level, timestamps, and output routing. In production these outputs cannot be aggregated or filtered.

Incorrect

def process(order):
    print("Processing:", order.id)
    return charge(order)

Correct

import logging

logger = logging.getLogger(__name__)

def process(order):
    logger.info("Processing: %s", order.id)
    return charge(order)

Fix

Replace print calls with a configured logging.Logger at the appropriate level.
