Creating a class, how does it work?

Question

Python

I can't understand why 7 is written in date

class SomeClass:
    def __init__(self, a):
        self.date = a
        print("Class created")
        print(self.date)


c = SomeClass(4 | 5 | 6 )

Answer 1

| is a bitwise OR operation
4 | 5 | 6 == 7 all correct
4 = 100
5 = 101
6 = 110
==> 111 = 7
That is, you create an object "c" of class SomeClass, which is passed the result of this operation.
