如何遍历类的所有属性？

class MyClass:
    def __init__(self):
        self.attribute1 = "value1"
        self.attribute2 = "value2"
        self.attribute3 = "value3"

my_object = MyClass()

# 获取对象的所有属性和方法
attributes = dir(my_object)

# 遍历所有属性并打印属性值
for attribute in attributes:
    if not attribute.startswith("__") and not callable(getattr(my_object, attribute)):
        print(f"{attribute}: {getattr(my_object, attribute)}")

attribute1: value1
attribute2: value2
attribute3: value3
