python type()和instance()區別

isinstance() function is used to judge one object is some type, this is familiar with function type()

the differences between isinstance() and type() is that isinstance() consider the inheritation.

class A:
    pass
 
class B(A):
	pass
 
isinstance(A(), A)    # returns True
type(A()) == A        # returns True
isinstance(B(), A)    # returns True
type(B()) == A        # returns False

isinstance() 與 type() 區別：

type() 不會認爲子類是一種父類類型，不考慮繼承關係。
isinstance() 會認爲子類是一種父類類型，考慮繼承關係。
