[BangPypers] Help required to design classes

[Saju M]

Hi Anand,

Sorry, I made a mistake in question
Note: constructor of class "A" and "P" doing different operations on input.

You are telling like this , right?

class BMixin:

class B(BMixin):

class Q(BMixin):

One more thing, class "B" should contain methods defined in class "A".
class "Q" should contain methods defined in class "P"  also.


So, can i do like this ???

class BMixin:

class B(BMixin, A):

class Q(BMixin, P):


Thanks,
