How are exceptions typically handled in Python?

In Python, exceptions are handled using try, except, and finally blocks, which provide a structured way to deal with errors that may occur during the execution of code. When a block of code is placed in a try clause, Python attempts to execute it. If an exception occurs, control is transferred to the except block, where the programmer can define how to handle the error. This flexibility allows for graceful error handling and prevents a program from crashing unexpectedly.

The finally block is optional but useful, as it will execute regardless of whether an exception was raised or not, allowing the programmer to clean up resources or perform any necessary final actions. This control structure promotes writing cleaner and more robust code, making it easier to manage potential runtime errors.

Other methods, such as using log statements, return statements, or global variables, do not effectively control the flow of execution in response to exceptions. Logging might help track errors but does not handle them. Return statements can bypass errors but do not address them at the source, and using global variables to reset states can lead to less maintainable and error-prone code. Hence, handling exceptions correctly with try, except, and finally blocks is a fundamental aspect of robust Python programming.
