13. Secure Use of Exceptions

Exceptions are helpful but can leak sensitive data if mishandled.

Insecure Example​

try:
    1 / 0
except Exception as e:
    print("Error:", e)  # Reveals system info

Secure Example​

try:
    1 / 0
except ZeroDivisionError:
    print("Cannot divide by zero.")

✅ Lesson: Catch specific exceptions. Avoid dumping stack traces to users.
