we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...

class 表示当前操作的对象属于哪个类。 这两者也是Python内建,无需自定义。 __del__ 析构方法,当对象在内存中被释放时,自动触发此方法。 注:此方法一般无须自定义,因为Python自带内存分配和释放机制,除非你需要在释放的时候指定做一些动作。析构函数的调用是由解释器在进行垃圾回收时自动触发执行的。 __call_...

Common Mistake #10: Misusing the__del__method Let’s say you had this in a file calledmod.py: import fooclassBar(object): ...def__del__(self): foo.cleanup(self.myhandle) And you then tried to do this fromanother_mod.py:
The .__call__() method will be called instead of the decorated function. It does essentially the same thing as the wrapper() function in your earlier examples. Note that you need to use the functools.update_wrapper() function instead of @functools.wraps.This @CountCalls decorator works the...
