Consider the following class definitions:

class A:

def $($self$,$ par $=2$ :

print $("/bar()",$ end $=")$

print$($par$)$ if par is not None else print$(2)$

par $=2$

class $B(A)$ :

def $($self$,$ par$)$:

print $("$B$",$ end $="")$

par

Consider the following class definitions: class A: def init (self, par = 2): print ("A", end "") print (par) if par is not None else print (2) par = = 2 class B (A): def = init (self, par): print ("B", end = " ") y = A (par) What will be happen when the following statement is executed: obj = B (4)
