Python中查看变量的类型内存地址所占字节的大小

#利用内置type()函数
>>> nfc=["Packers","49"]
>>> afc=["Ravens","48"]
>>> combine=zip(nfc,afc)
>>> type(combine)
<class 'zip'>

#利用内置函数id(),是以十进制显示
>>> id(nfc)
2646554913160
>>> id(afc)
2646554913544

>>> import sys
>>> print(sys.getsizeof(combine))
64
>>> print(sys.getsizeof(nfc))
80
>>> print(sys.getsizeof(afc))
80 

id(object) -> integer
Return the identity of an object. This is guaranteed to be unique among
simultaneously existing objects. (Hint: it's the object's memory address.)
