How to iterate through objects in a class?

For a script I’m writing I would like to be able to something like this.

class foo:
    __init__(self):
        self.a = 'path1'
        self.b = f'{self.a}path2'

bar = foo()

for i in bar:
    if not os.path.isdir(i):
        os.mkdir(i)

But I can’t quite figure out how to make the class iterate through the objects.

(Please forgive any typos. Typing this up quickly on my phone)

>Solution :

Is this what you need?

class foo:
    def __init__(self):
        self.a = 'string1'
        self.b = f'{self.a}string2'

bar = foo()

for attr, value in bar.__dict__.items():
        print(attr, value)
