printing variable fom a Class in Python

I am a newbie in Python and playing around with the classes right now,

Have a look at this simple code,

class Testing:

    BB_Key_Length = {256 : 240}

#method __init__() is a special method, which is called class constructor or initialization method that 
#Python calls when you create a new instance of this class.    
    def __init__(self, key_length):
        self._key_length = key_length
        self._n = int(key_length / 8)

        if key_length in self.BB_Key_Length:
            self._b = self.BB_Key_Length[key_length]
            print(self._b)


Object1 = Testing(200)
print(Testing.BB_Key_Length)

on line 13, it is written that, print(self._b) which is also inside the __init__ function but why the value of self._b is not printing when I am creating the object 

Object1 = Testing(200)

All I want is to print the value of self._b which i couldn't be able to print

Because the print statement is inside an if statement, which is false because 200 is not a key in the dict self.BB_Key_Length.
