如何在Python中的类之间创建共享类属性

class MyClass:
    shared_attribute = "Shared Value"

    def __init__(self, instance_attribute):
        self.instance_attribute = instance_attribute

    def print_attributes(self):
        print("Shared Attribute:", self.__class__.shared_attribute)
        print("Instance Attribute:", self.instance_attribute)

# 创建两个实例
obj1 = MyClass("Instance Value 1")
obj2 = MyClass("Instance Value 2")

# 访问和修改共享属性
print(obj1.shared_attribute)  # 输出: Shared Value
print(obj2.shared_attribute)  # 输出: Shared Value

obj1.shared_attribute = "Modified Value"

print(obj1.shared_attribute)  # 输出: Modified Value
print(obj2.shared_attribute)  # 输出: Shared Value

# 调用方法打印属性
obj1.print_attributes()
obj2.print_attributes()

Shared Value
Shared Value
Modified Value
Shared Value
Shared Attribute: Modified Value
Instance Attribute: Instance Value 1
Shared Attribute: Modified Value
Instance Attribute: Instance Value 2
