Understanding How Attributes Are Declared Outside the Constructor

For example, the code below is

class Something:
    a="<- This attribute and "

    def__init__(self):
        self.b="<- Different handling of this attribute."
        
print(Something.a)
print(Something.b)b)
        
sample=Something()
print(sample.a)
print(sample.b)

print(Something.b)The is an error (AttributeError: type object 'Something' has no attribute 'b').The print(Something.a) in the previous line prints <- This attribute and .
The b of the Something class could not be accessed without creating an instance, but a could be accessed without creating an instance.
