If an IRQ exception occurs, when other IRQ interrupts occur, the CPU will not respond; when an FIQ interrupt occurs, the current interrupt handling task will be stopped first to handle the FIQ interrupt, and then jump back to handle the IRQ interrupt. If an FIQ exception occurs, the proces...

except Exception as e: # Handle other exceptions finally: # Cleanup, runs no matter what 异常是按层次结构组织的,如果发生了IOError会执行IOError的except代码,剩下的异常则交由Exception处理。理解这个层次结构可以根据需要更广泛或更具体地捕获错误。 使用finally子句确保执行清理操作,而不管是否发生异常。它非常...

Exceptioncan be used as a wildcard that catches (almost) everything. However, it is good practice to be as specific as possible with the types of exceptions that we intend to handle, and to allow any unexpected exceptions to propagate on. ...

Because the program abruptly terminates on encountering an exception, it may cause damage to system resources, such as files. Hence, the exceptions should be properly handled so that an abrupt termination of the program is prevented. Python uses try and except keywords to handle exceptions. Both ...
