How do you call an instance of a class in Python?

This is inspired by a question I just saw, "Change what is returned by calling class instance", but was quickly answered with __repr__ (and accepted, so the questioner did not actually intend to call the instance). Now calling an instance of a class can be done like this: instance_of_object = object() instance_of_object() but we'll get an error, something like TypeError: 'object' object is not callable . This behavior is defined in the CPython source here. So to ensure we have this question on Stackoverflow: How do you actually call an instance of a class in Python? You call an instance of a

Somehow I couldn't find information about it via google. And furthermore, what does it mean if I get a Trace/breakpoint exception when running an x86 assembly program which has such an instruction? 回答1: Intel and AMD publish very good documentation regarding x86. Here's a link to Intels instruction set

iOS: showing an alert when getting a call?

由 无人久伴 提交于 2019-11-29 15:44:16
问题 I would like a local notification to be fired when a call is received (and to show an alert) - is this possible? Can a call event get an app to launch or a notification to be fired? How is skype fired? With push notifications? Thanks 回答1: If your application is running while a call is in place check out the CoreTelephony Framework. The CTCall class provides information about the call state. I have not used this myself but you may find it useful. extern NSString const *CTCallStateDialing;
