List attributes of an object

In Python, you can use the built-in function dir() to list the attributes of an object. Here's an example of how you can use it:

Using the built-in dir() function to list attributes of an object in Python

class MyClass:
    def __init__(self):
        self.x = 5
        self.y = 10

obj = MyClass()
print(dir(obj))

This would output:

attributes output

['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'x', 'y']

Note that dir() also returns the built-in attributes of the object, in addition to the attributes that you defined in the class. If you only want to see the attributes that you defined, you can use vars() function.

Returns the built-in attributes of the object, in addition to the attributes that you defined in the class

print(vars(obj))

This would output:

next output

{'x': 5, 'y': 10}
