In Python 3, error handling is managed through , which are events that disrupt the normal flow of a program . Mastering these tools allows you to create robust applications that can recover from issues like invalid user input or missing files instead of crashing. The Core Mechanism: try...except
: For domain-specific logic, you can define your own error classes by inheriting from the built-in Exception class.
try: number = int(input("Enter a number: ")) result = 10 / number except ValueError: print("Error: Please enter a valid integer.") except ZeroDivisionError: print("Error: Cannot divide by zero.") Use code with caution. Copied to clipboard Expanding Control: else and finally
: Avoid using a bare except: or except Exception: . Catching specific errors (e.g., FileNotFoundError ) prevents you from accidentally silencing unexpected bugs you didn't intend to handle.
