Hello Python Experts,


Dear Python experts,?

Please can you help in a following scenario..?
I have some classes each for a Protocol Data Unit which you could consider as a structures o
f elements?
example?
class ex1:?
class usr_mac(MAC_PDU):?
? ? 
? ? def __init__(self):?
? ? ? ? self.pf = BV.Bit1.new()?
? ? ? ? self.res = BV.Bit1.new()?
? ? ? ? self.flco = ?BV.Bit6.new()?
? ? ? ? self.grpad = BV.Bit24.new()?
? ? ? ? self.srcad = BV.Bit24.new()?
? ? ? ? self.order = ['protectFlag',?
? ? ? ? ? ? ? ? ? ? ? 'reserved',?
? ? ? ? ? ? ? ? ? ? ? 'flco',?
? ? ? ? ? ? ? ? ? ? ? 'grpad ',?
? ? ? ? ? ? ? ? ? ? ? 'srcad '] 

Another message (transport layer)
class Info_req_msg(MAC_PDU):?

? ? 
whose elements are 
1. msg_type
2. msg_size
3. PDU ( in this case, i need to send instance of "usr_mac"? defined above)

can you please help me. 


Now i have a another message which i need to create similar but now it contains the above cl
ass instance as one of the members.?

Please can you tell me how to pass instance of above class as a member of the new message cr
eated in similar lines with one of the elements is the complete data above (instance of abov
e class).?

I am encapsulating above message in a transport layer message.?
2. Now similarly, i would like given a choice to choose the instance of other class as the i
 would like to pass ?in other instance of class similarly.?

Your kind help will be greatly appreciated. Please let me know if there are clarifications i
 can give, I am posting this in a hurry. I am sure there could be questions.?

Thanks in advance?
