Python Exception Handling Quiz

Exception Handling in Python

• The purpose of an exception in Python is to handle errors that occur during program execution.
• A OverflowError is raised when a calculation exceeds the maximum limit for a numeric type in Python.
• An IndexError is raised when an index is not found in a sequence.
• A NameError indicates that a variable or name is not defined in Python.
• An ImportError occurs when a module or package cannot be imported in Python.
• A ZeroDivisionError is raised when a division by zero is attempted in Python.
• The try block in exception handling is used to enclose a section of code that might raise an exception.
• The except statement in Python's exception handling is used to catch and handle exceptions.
• The else block in a try-except statement is executed when no exception is raised in the try block.
• Using except with no exceptions defined is not considered good programming practice because it can catch all exceptions, including system exceptions, and make debugging difficult.
• If an error occurs while writing content to a file, it will not be written to the file.
• The except block of code executes if an exception occurs in a try block.
• A FileNotFoundError is raised when trying to open a file that does not exist.
• The try block is used to enclose a section of code that might raise an exception.
• The except statement catches and handles exceptions.
• The else block executes if no exception is raised in the try block.
• A generic except clause catches all exceptions, including system exceptions.
• A single try statement can have multiple except statements to handle different types of exceptions.
• When an exception is thrown in the try block, the execution of the try block stops, and the except block is executed.
• Exceptions can be handled after their occurrence using a try-except statement.
• The finally block ensures that resources, such as files, are closed or released, regardless of whether an exception is thrown.
• The raise statement is used to raise exceptions in Python.
• The traceback argument in the raise statement provides information about the exception, such as the call stack.
• The finally block should be used to close a file opened within a try block.
• The except clause with multiple exceptions can be used to catch and handle multiple exceptions.
• The finally block in the try-finally clause ensures that resources are released, regardless of whether an exception is thrown.
• Both except and finally clauses can be used together in Python.
• If an exception occurs within a try block and there is no except or finally clause to handle it, the program terminates.
• When using else and finally clauses together, the finally block is executed after the else block.
