The difference between functions and methods in Python

1, the function to manually pass self, the method does not have to pass self

2, if it is a function, with the class name to call, if it is a method, with the object to call

To illustrate:

Class Foo (object):    def __init__ (self):        self.name= "Haiyan"    def func:        print (self.name) obj = Foo () Obj.func () foo.func (obj)

Ways to judge functions and methods

From types Import functiontype,methodtypeobj = Foo () print (Isinstance (obj.func,functiontype))  #Falseprint ( Isinstance (Obj.func,methodtype))   #True   #说明这是一个方法print (isinstance (foo.func,functiontype))  #True   #说明这是一个函数. Print (Isinstance (foo.func,methodtype))  #False
