Tocatch exceptions, a part of the code is kept underinspection. This is done by closing that part of the code in a try-block. When an exceptional circumstance arises within that block, anexceptionis thrown and an exception handler takes control over the program. How to throw an exception i...
An exception handler is code that stipulates what a program will do when an anomalous or exceptional event occurs and disrupts the normal flow of that program'sinstructions. A software program, regardless of the language it is written in, is meant to run a specific way and generate a certain...
Exception handling is useful for dealing with exceptions that cannot be handled locally. Instead of showing an error status in the program, theexception handlertransfers control to where the error can be handled. A function can throw exceptions or can choose to handle exceptions. Error handling cod...
A normal computer runs a number of processes continuously to help manage the operating system (OS), the hardware and the applications installed on the machine. This can range from a simple background task like a spell-checker or system event handler to a full-fledged application such as Micros...

often triggered by external devices. When an interrupt occurs, the program counter is temporarily saved, and the central processing unit (CPU) jumps to an interrupt handler routine. After handling the interrupt, the program counter is restored to its original value, allowing the interrupted program...

The exception handler chosen is said to catch the exception. If the runtime system exhaustively searches all the methods on the call stack without finding an appropriate exception handler, as shown in the next figure, the runtime system (and, consequently, the program) terminates. Searching the...

For example, if your function runs in the Python 3.9 runtime, you must add specific code to run your handler. The content of the red box in the following figure shows the sample code. When I modify function code, git displays code differences. Is this because function code is hosted by...
