Unused Imports in Python: Why They Matter
Every import adds load time. In large projects with dozens of unused imports this has a measurable impact and misleads developers about true dependencies.
❌ Code with Unused Imports
import os
import re
import json
import datetime # Never used
from collections import OrderedDict # Never used
def get_config(path):
with open(path) as f:
return json.load(f)✅ Cleaned Import Section
import json # Only import what you actually use
def get_config(path):
with open(path) as f:
return json.load(f)💡
Pro tip: Add flake8 --select=F401 to your CI to fail builds with unused imports. Use autoflake to remove them automatically.
