random_multinomial_choice() function seems not right

[fuxuemingzhu]

I am confused about the random_multinomial_choice() function in your train_cbow_weighted.py file. The condition of if sentence seems not right.. More likely, if y>=x: should be here. In my opinion, if the play time of a game is quite bigger, this game should be return. Am I right? Waiting for your reply.

And here is your code.

def random_multinomial_choice(tuples):
    x = random.random()
    total = sum([hours for _, hours in tuples])
    for game, hours in tuples:
        y = hours / total
        if y <= x:
            return game
        x -= y
    return tuples[-1][0]
