普通类函数，@classmethod，@staticmethod，@property，@some_property.setter函数认识

# coding=utf-8
class MyClass(object):
    def __init__(self):
        self._some_property = "properties are nice"
        self._some_other_property = "VERY nice"

    def normal_method(*args, **kwargs):
        print("{0},{1}".format(args, kwargs))

    @classmethod
    def class_method(*args, **kwargs):
        print("{0},{1}".format(args, kwargs))

    @staticmethod
    def static_method(*args, **kwargs):
        print("{0},{1}".format(args, kwargs))

    @property
    def some_property(self, *args, **kwargs):
        print("{0},{1},{2}".format(self, args, kwargs))
        return self._some_property

    @property
    def some_other_property(self, *args, **kwargs):
        print("{0},{1},{2}".format(self, args, kwargs))
        return self._some_other_property

    @some_property.setter
    def some_property(self, *args, **kwargs):
        print("{0},{1},{2}".format(self, args, kwargs))
        self._some_property = args[0]


o = MyClass( )
# 1.普通函数——》省略了self，所以会把第一个参数作为类的实例（就像是self，可以自定义）
print(o.normal_method)  # <bound method MyClass.normal_method of <__main__.MyClass object at 0x000002F090756748>>
print(o.normal_method( ))  # (<__main__.MyClass object at 0x000001707D686748>,),{}
print(o.normal_method(1, 2, x = 3, y = 4))  # (<__main__.MyClass object at 0x000001707D686748>, 1, 2),{'x': 3, 'y': 4}

# 2.类函数——》类方法的第一个参数永远是该类的实例
print(o.class_method)  # <bound method MyClass.class_method of <class '__main__.MyClass'>>
print(o.class_method( ))  # (<class '__main__.MyClass'>,),{}
print(o.class_method(1, 2, x = 3, y = 4))  # (<class '__main__.MyClass'>, 1, 2),{'x': 3, 'y': 4}

# 3.静态方法——》除了你调用时传入的参数以外，没有其他的参数
print(o.static_method)  # <function MyClass.static_method at 0x000001725F2A4F78>
print(o.static_method( ))  # (),{}
print(o.static_method(1, 2, x = 3, y = 4))  # (1, 2),{'x': 3, 'y': 4}

# 4.默认是获取类属性的函数
print(o.some_property)
# <__main__.MyClass object at 0x000001B7AF701E48>,(),{}
# properties are nice

# 5.默认是获取类属性的函数
print(o.some_other_property)
# <__main__.MyClass object at 0x000002948A091DC8>,(),{}
# VERY nice

# 6.设置类属性的函数
test = o.some_property = "groovy"
print(test)
# <__main__.MyClass object at 0x000001D3518A1E88>,('groovy',),{}
# groovy
