Rock Paper Scissors with scores and save file

I've implemented the classic game Rock Paper Scissors with scores, and a save file implementation. I'm looking particularly for ways to get rid of all the self.'s. Is there anything I should add, remove, or change. Are there any bugs? Anything else?

```
#Programmer:
import random as ran
import shelve

class Score(object):
"""Place where all scores are stored for save document"""

def __init__(self):
"""Makes all variables set to 0"""
self.rounds = 0
self.losses = 0
self.wins = 0
self.draws = 0
self.game_wins = 0
self.game_losses = 0
self.total_rounds = 0
self.total_games = 0
self.round_wins = 0
self.round_losses = 0
self.round_draws = 0

def reset(self):
"""Resets the scores for next game"""
self.wins = 0
self.draws = 0
self.losses = 0

def tally(self):
"""Adds the score to stats"""
self.total_rounds += self.rounds
self.total_games += 1
self.round_wins += self.wins
self.round_losses += self.losses
self.round_draws += self.draws

def stats(self):
"""Prints the stats"""
print ('\n\n+++++++++++++++++++++-=Stats=-+++++++++++++++++++')
print ('=================================================')
print ('|-- --|-- Rounds --|-- Games --|')
print ('|-- Wins --|-- %s --|-- %s --|') %(self.round_wins, self.game_wins)
print ('|-- Losses --|-- %s --|-- %s --|') %(self.round_losses, self.game_losses)
print ('|-- Draws --|-- %s --|-- N/A --|') %(self.round_draws)
print ('|-- Played --|-- %s --|-- %s --|\n\n')%(self.total_rounds, self.total_games)

def final(self):
"""Prints final score of the game just played"""
print ('\n\n+++++++++++Final Score++++++++++')
print ('===========================

Proper error catching

Never, ever have an empty except clause like the following:

try:
    ...
except:
    ...

With an empty except clause, any error that occurs in the try block will be caught by the except clause. This includes errors that aren't intended to be caught, like a SystemError, where something goes wrong internally.

The proper way to specify what error you want to catch would be to write your except clause like this:

except ExceptionType:
    ...

Properly opening files

The generally accepted method for opening files in Python is to use a contest manager, as seen below. If you use a context manager, the file is closed implicitly, and you can guarantee that the file is closed properly if the program unexpectedly exits:

with open("path/to/my/file.dat", "mode") as my_file:
    ...

OOP Design

It feels like you're not using object-oriented-programming correctly, as your __init__ methods seem to be doing way too much. As the name implies, the magic method __init__ should only be used for class initialization, and nothing else. Right now, you're treating the __init__ method like the "main method" of your class.

The best way that I can think of would be to do two things:

• Use a global state. I wouldn't highly recommend this, but if the program is small and trivial enough, then it's probably okay.

• Represent items like a Scissor, or a Rock with objects.

Nitpicks

-
Classes in Python 3.x are implicitly new-style, and don't need to explicitly inherit from object. This means they can be declared in a fashion like this:

class MyClass:
    ...

-
Functions like stats() or final() should probably return a string, rather than explicitly printing one.
