Catch Specific Exceptions<\/h2>\n<p>Always catch specific exception types like <code>ValueError<\/code> or <code>TypeError<\/code> instead of using a bare <code>except:<\/code>. This avoids hiding unexpected bugs.<\/p>\n<pre><code>try:\n    result = int(value)\nexcept ValueError:\n    print(\"Invalid number\")\n<\/code><\/pre>\n<h2>2. Use <code>else<\/code> and <code>finally<\/code><\/h2>\n<p>The <code>else<\/code> block runs when no exception occurs, while <code>finally<\/code> always executes for cleanup. This structure makes your intent clear.<\/p>\n<pre><code>try:\n    data = process()\nexcept ConnectionError:\n    retry()\nelse:\n    save(data)\nfinally:\n    close_connection()\n<\/code><\/pre>\n<h2>3. Never Use Bare <code>except:<\/code><\/h2>\n<p>A bare <code>except:<\/code> catches everything, including <code>KeyboardInterrupt<\/code> and <code>SystemExit<\/code>. If you must catch all ordinary errors, use <code>except Exception<\/code>.<\/p>\n<ul>\n<li>It masks critical errors<\/li>\n<li>It makes debugging difficult<\/li>\n<li>Always log or re-raise if ignoring<\/li>\n<\/ul>\n<h2>4. Log Exceptions with Context<\/h2>\n<p>Use <code>logging.exception()<\/code> to capture the full traceback along with your message. This gives you actionable information for debugging.<\/p>\n<pre><code>try:\n    load_file()\nexcept FileNotFoundError as e:\n    logging.exception(\"Failed to load: %s\", e)\n<\/code><\/pre>\n<p>Following these best practices will make your Python code more robust, readable, and maintainable.
