Don't be discouraged. Your central program was very nearly right and your mistakes are just the normal kinds of mistakes that beginners make so you are basically on the right track. > Any way, can you please help and guide me to get done this.

I would just set one, the important thing is that you should always set default values to the same type as the real values. In this case that means a string. You could even use an empty string "" if you like. > 2. For this command pc = random.choice( > list(game_command.keys())[:3]), I don't really how to control.

Yes, that is the problem, most of the time these things will work but you cannot guarantee it. In this case, because there are only 3 values, you could just use the values directly: pc = random.choice( ['r','p','s']) If you really prefer a variable, and it is better practice, then you can change your variable definitions: weapons = ['r','p','s'] choices = weapons + ['e'] game_command = dict(zip(choices,['Rock','Paper','Scissors','Exit'])) then use pc = random.choice( weapons ) > 3. Is there any problem if I didn't print the player score when PC won? The specification asked for the score to be printed: ------------------------------- For the game result the program must return details of the following: - The user’s selection - The computer’s selection - The winning hand - A running total of user wins including this game and previous games ------------------ It did not say to only do that if the player won... > 4. Also how the exception to be generated. Test the input value is valid and if not, use: raise ValueError The value is not valid if it is not in choices.... -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
