Need help in below example of class and function !

Question

Can someone help in describing below code, step by step, why the output will be 4?

class FirstClass:
n = 4
def __init__(self, n):
n = n // 4
print(n)
a = FirstClass(8)
print(a.n)

Answer 1

At a glance, it seems that in the init function you'll get 2 out, but no assignment to the class variable takes place (should be self.n = n // 4. The left side of = is the class variable and the right side is the local parameter of the init function.)

When you access a.n it's still 4, as declared above
