print_class_attributes(my_instance) 1. 总结 综上所述,我们可以按照以上步骤来实现"Python打印class所有属性"的操作。下面是完整的代码示例: importinspectdefprint_class_attributes(cls):attributes=inspect.getmembers(cls,lambdaa:not(inspect.isroutine(a)))forattributeinattributes:print(attribute)classMyClass:de...

类(Class)是用来描述具有相同的属性和方法的对象的集合,而实例(Instance)则是基于类所创建的具体的对象(Object)。 创建类 使用class关键字和类名来创建一个新类,后面为缩进块来实现类的内容,即类的属性(Attributes),包括变量(Data、Property)和方法(Method)。 在类的定义中,习惯上用 self表示类实例本身,因而,下...
要打印对象的属性,可以使用内置的dir()函数来获取对象的属性列表,然后使用getattr()函数来获取每个属性的值并打印出来。以下是一个示例: class Person: def __init__(self, name, age): self.name = name self.age = age person = Person("Alice", 30) # 获取对象的属性列表 attributes = dir(person) ...
name, self.age)...>>> bob = Person("Robert", 35) # Create a Person instance>>> joe = Person("Joseph", 17) # Create another>>> joe.sport = "football" # Assign a new attribute to one instance>>> dir(Person) # Attributes of the Person class['__class__', '__del...
示例代码：class MyClass:"""A simple example class（一个简单的示例类）"""i = 12345def f(self):return 'hello world'x = MyClass()说明原文：Valid method names of an instance object depend on its class. By definition, all attributes of a class that are function objects define corresponding ...
print getattr(dog, 'run') print getattr(dog, 'd') 2.hasattr() hasattr(object,name)¶ The arguments are an object and a string. The result isTrueif the string is the name of one of the object’s attributes,Falseif not. (This is implemented by callinggetattr(object,name)and seeing ...
