Catching every single error in Python feels safe, but a bare `except:` block is quietly wrecking your code. In this video you’ll see exactly why it’s so dangerous, and the four fixes that turn fragile scripts into robust, production-ready ones.
We cover:
– Why a bare `except:` hides real bugs like a simple NameError
– How it traps Ctrl+C (KeyboardInterrupt) and SystemExit, so you can’t even stop your program
– Why swallowed errors give you no traceback and become a silent production nightmare
Then the fixes:
1. Catch specific exceptions (e.g. FileNotFoundError), not everything
2. If you must be broad, use `except Exception` (never a bare except) β it leaves KeyboardInterrupt and SystemExit alone
3. Never fail silently β log the error with its full traceback using logging.exception()
4. Always clean up with `finally`, or better, a `with` statement β plus re-raising and the `else` block
Master these and your error handling goes from a liability to a superpower.
