Once the runtime system receives the exception object, it searches through the next layers, seeking exception handler code that matches what is specified in the exception object. Here, the system's goal is to find the code (or rather, the block of code) through an ordered list of methods ...
When an unexpected condition occurs, Python creates an exception object that consists of information about the type, message, and location in the program. The programmer must add an exception handler in the code; if the handler is found, the exception is processed; otherwise, Python’s default ...

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...
PEP 3134: Exception chaining. There are two cases: implicit chaining and explicit chaining. Implicit chaining happens when an exception is raised in an except or finally handler block. This usually happens due to a bug in the handler block; we call this a secondary exception. In this case, ...

A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to define asynchronous generators: async def ticker(delay, to): """Yield numbers from 0 to...
This is useful for those writing CPython extensions. It enables more explicit runtime checks on how CPython allocates and frees memory internally. Enabling the faulthandler module, so that tracebacks are always dumped after a crash. Python time functions with nanosecond resolution A new class...
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...
