Study Notes

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.
