Learn python class methods and object methods, and learn python class objects

This article provides an example of studying the class and object methods of python. The details are as follows:

Class Test_Demo: TEST = 'test _ value' def _ init _ (self, name, age): self. name = name self. age = age # static method @ staticmethod def test_static (): return Test_Demo.TEST # feature @ property def test_property (self): return self. name + ':' + str (self. age) # class method @ classmethod def test_class (self): return self. TESTif _ name _ = '_ main _': test_demo = Test_Demo ('zj', 23) # print (test_demo.name) print (Test_Demo.test_static ()) print (test_demo.test_property) print (test_demo.test_class ())

Output result:

Note: Unlike php:

Class and static methods can be used to initialize static variables (class variables, TEST) of the class, but neither of them can access instance variables (that is, name, age)

If the access is successful, an error is returned:
