__del__:在需要销毁实例的时候,python解释器会调用__del__方法。Cpython中垃圾回收的主要算法是引用计数,每个对象会统计有多少引用指向自己。当引用计数归零时,对象立即就被销毁

Writing code that runs on both Windows and Unix systems always has challenges but thankfully worrying about printing \n versus \r\n isn’t one of them. Theprint()function is smart enough to convert \n to \r\n when running on Windows. Using os.linesep Theprint()function may convert \n...
Back in Section 4.1 you saw that assignment works on values, but that the value of a structured object is a reference to that object. The same is true for functions. Python interprets function parameters as values (this is known as call-by-value). In the following code, set_up() has...
