Key python.quality.magic-number · Severity info · Category quality

Bare numbers embedded in code hide their meaning and force a hunt across the codebase when they change. Move them into named constants.

Incorrect

def session_expired(last_seen):
    return time.time() - last_seen > 1800

Correct

SESSION_TIMEOUT_SECONDS = 1800

def session_expired(last_seen):
    return time.time() - last_seen > SESSION_TIMEOUT_SECONDS

Fix

Extract meaningful numeric literals into clearly named module constants.
