Number类型包含:int、float、bool、complex(复数) 注意: 在python3中,bool是int的子类;在值方面,True==1、False==0,当然,它们的id(内存地址)不同,仅是值相同;布尔类型可以和数字类型进行相加减。而python2中没有布尔类型,用0和1来进行表示。 >>>True+34>>>False-3-3>>>True+3.24.2>>>id(True) ==i...
>>> callable('hello') False >>> callable(sorted) True >>> callable(bool) True class A: def test(self): print('test') class B: def __call__(self, *args, **kwargs): pass def test(self): print('1') a = A() b = B() print(callable(A)) # True print(callable(B)) # ...

Boolean (or bool). Is 0 true or false in Python? Python assigns boolean values to values of other types. For numerical types like integers and floating-points,zero values are falseand non-zero values are true. Is 0 True or false?
Classes are a way to bundle functionality and state together. The terms "type" and "class" are interchangeable:list,dict,tuple,int,str,set, andboolare all classes. You'll certainly use quite a few classes in Python (remember typesareclasses) but you may not need to create your own often...
In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
