我知道如何迭代对象的属性。但这不包括通过 getter/setter 或 @property 装饰器实现的属性。
我如何迭代这些?
class MyClass:
def __init__(self):
self.foo = "bar"
@property
def myprop(self):
return "hello"
my_instance = MyClass()
for i in my_instance.__dict__:
print("object has attribute %s" % i)
这个小脚本打印:
object has attribute foo
我想要的是一个打印的脚本:
object has attribute foo
object has attribute myprop
最佳答案
您可以使用dir()
来获取所有属性,尽管这将包括从基类继承的方法,包括来自对象的所有dunder方法:
class MyClass:
def __init__(self):
self.foo = "bar"
@property
def myprop(self):
return "hello"
my_instance = MyClass()
for i in dir(my_instance):
print("object has attribute %s" % i)
打印:
object has attribute __class__
object has attribute __delattr__
object has attribute __dict__
object has attribute __dir__
object has attribute __doc__
object has attribute __eq__
object has attribute __format__
object has attribute __ge__
object has attribute __getattribute__
object has attribute __gt__
object has attribute __hash__
object has attribute __init__
object has attribute __init_subclass__
object has attribute __le__
object has attribute __lt__
object has attribute __module__
object has attribute __ne__
object has attribute __new__
object has attribute __reduce__
object has attribute __reduce_ex__
object has attribute __repr__
object has attribute __setattr__
object has attribute __sizeof__
object has attribute __str__
object has attribute __subclasshook__
object has attribute __weakref__
object has attribute foo
object has attribute myprop
您可以使用字符串操作排除一些:
for i in dir(my_instance):
if i.startswith("__"):
continue
print("object has attribute %s" % i)
打印:
object has attribute foo
object has attribute myprop
