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...
d = {'a': 1, 'b': 2} if 'c' in d: print True # DO NOT USE if d.has_key('c'): print True for key in d: print key # DO NOT USE for key in d.keys(): print key Python的dict对象是对KEY做过hash的,而keys()方法会将dict中所有的KEY作为一个list对象;所以,直接使用in的时候...

通过实现特殊方法__len__和__getitem__,我们的FrenchDeck表现得像一个标准的 Python 序列,允许它从核心语言特性(例如迭代和切片)和标准库中受益,如使用random.choice、reversed和sorted的示例所示。得益于组合,__len__和__getitem__实现可以将所有工作委托给一个list对象self._cards。
