List attributes of an object

🕵️‍♀️ The Quest for Object Attributes

So, you find yourself on a mission to grab a list of attributes that exist on instances of a class, huh? 🤔 No worries, fellow explorer! We're here to guide you through this perplexing puzzle and help you uncover the desired results. 🌟

🎯 The Problem

Your mission is to obtain a list of attributes from instances of a class using Python. In other words, you want to extract the attributes "multi" and "str" from the new_class object, "a".

📝 The Solution

1. To start, let's take a look at the code snippet you provided:

class new_class():
    def __init__(self, number):
        self.multi = int(number) * 2
        self.str = str(number)

a = new_class(2)
print(', '.join(a.SOMETHING))

1. In order to retrieve the attributes, we'll use the dir() function. This handy function returns a list of valid attributes and methods for an object.

class new_class():
    def __init__(self, number):
        self.multi = int(number) * 2
        self.str = str(number)

a = new_class(2)
attributes_list = dir(a)
print(attributes_list)

1. Now, if you only want to display the attributes and not the methods, you can filter the list using a simple list comprehension and the hasattr() function:

class new_class():
    def __init__(self, number):
        self.multi = int(number) * 2
        self.str = str(number)

a = new_class(2)
attribute_names = [attr for attr in dir(a) if not callable(getattr(a, attr)) and not attr.startswith("__")]
print(", ".join(attribute_names))

💡 Voila! The desired result will now be printed: "multi, str".
