trouble with classes in python -

i getting error reads , no matter unable rid of code.

traceback (most recent call last):   file "c:\users\ian\desktop\blackjack.py", line 226, in <module>     main()   file "c:\users\ian\desktop\blackjack.py", line 225, in main     blackjack.playgame()   file "c:\users\ian\desktop\blackjack.py", line 145, in playgame     self.firstround()   file "c:\users\ian\desktop\blackjack.py", line 83, in firstround     a=self.dealer.hand.append(deckofcards.deal(deckofcards.shuffledeck)) attributeerror: type object 'deckofcards' has no attribute 'shuffledeck' 

the following actual code have written ( have changed great deal in order move error along can no longer figure out going on) want skim on , tell me obvious mistakes, sure there many, , apologize our professor doesn't teach use how things , expects know how.

this line right 1 problem:

a=self.dealer.hand.append(deckofcards.deal(deckofcards.shuffledeck)) 

• append returns none (regardless of append), a none
• deckofcards refers class object, not instance of class. want use self.deck instead of deckofcards.

x==card('s','a'): isn't going work either. haven't defined __eq__ card object, comparisons don't work (you'll false).
