Bug Detection
Detect Bugs in Python: Common Patterns and Fixes
Python's dynamic typing makes it easy to introduce subtle bugs that only surface at runtime. Knowing the most common patterns helps you catch them early.
❌ Common Bug: Wrong Module Import
import sqlite2 # Module does not exist
conn = sqlite2.connect('database.db')✅ Corrected Import
import sqlite3 # Correct standard library module
conn = sqlite3.connect('database.db')💡
Pro tip: Use flake8 and mypy in your CI pipeline to catch import errors, type mismatches, and undefined variables before they reach production.
