Getting a "Cannot be Opened"" error Message

[valerydolce]

Buran/oFnuts,
Per your advise, I changed the code as shown below and i got a bunch of error

def team_average(filename):
        numberOfGames = 0
        soxWins = 0
        try:
                file = open(filename, 'r')
        except:
                print (filename, "Cannot be opened")
        else:
                for line in file:
                        numberOfGames += 1
                        game = line.split()
                        scores = game[1]
                        scores_list = scores.split('-')
                        for score in scores_list:
                                if (int(score[0]) - int(score[1]) > 0:
                                        soxWins += 1
                average_win = int(soxWins/numberOfGames) * 100

team_average('xxxxxx')
print(team_average('red_sox.txt'))

and below is the error i got :
